Antonio Maiorano 06feb3f287 Finish moving call validation from Validator to Resolver
Call validation was already implemented in Resolver. This change
completes it by deleting the relevant code in Validator, and moving and
updating the builtins validation test to use the Resolver.

Also added the "v-0004" error code for when detecting recursion, as was
done for the similar error in the Validator.

Ben Clayton eae161cd9f writer/spirv: Clean up constant generation
Requiring a temporary stack-allocated ast::Literal is an unpleasant requirement to generate a SPIR-V constant value.
GenerateU32Literal() was also creating an invalid AST - the type was U32, yet an an ast::SintLiteral was used.

Instead add Constant for holding a constant value, and use this as the map key.

This also removes the last remaining use of ast::NullLiteral, which will be removed in the next change.

* Fixed many tests that now failed validation. Most of the time,
functions declared that they returned a type, but with no return
statement.

* ProgramBuilder: Added Return function to create ast::ReturnStatements

Ben Clayton 767df5f03b Fix infinite spin in wgsl parser
If the parser hits a `maximum parser recursive depth reached` situation, then we need to try and resynchronize the parser.

If we fail to do this, then the synchronized_ flag may remain true, and the parser will believe progress is still being made.
In this situation the parser may try to reparse the same token, forever.

By calling sync_to() we either find the end of the block, and forward progress can be made, or synchronized_ is set to false, and the parser can error out cleanly.

Add test case from fuzzer report.

This fixes issues where the reording might generate an invalid WGSL

This also unifies the implementation of Generate() and
GenerateEntryPoint(), to avoid implementing the same logic twice.

Ben Clayton 59d24735d0 Add IntrinsicTable
Provides a centeralized table for all intrinsic overloads.

IntrinsicTable::Lookup() takes the intrinsic type and list of arguments, returning either the matched overload, or a sensible error message.

The validator has expectations that the TypeDeterminer resolves the return type of an intrinsic call, even when the signature doesn't match. To handle this, create semantic::Intrinsic nodes even when the overload fails to match. A significant portion of the Validator's logic for handling intrinsics can be removed (future change).

There are a number of benefits to migrating the TypeDeterminer and Validator over to the IntrinsicTable:
* There's far less intrininsic-bespoke code to maintain (no more duplicate `kIntrinsicData` tables in TypeDeterminer and Validator).
* Adding or adjusting an intrinsic overload involves adding or adjusting a single Register() line.
* Error messages give helpful suggestions for related overloads when given incorrect arguments.
* Error messages are consistent for all intrinsics.
* Error messages are far more understandable than those produced by the TypeDeterminer.
* Further improvements on the error messages produced by the IntrinsicTable will benefit _all_ the intrinsics and their overloads.
* The IntrinsicTable generates correct parameter information, including whether parameters are pointers or not.
* The IntrinsicTable will help with implementing autocomplete for a language server

The reason we need the sem_ prefix is because all the tint lib code is compiled as a single target, and .GN cannot cope with .cc files with the same file name, even if they're in different directories.

Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.

Follows the basic shallow-clone pattern of type::Manager::Wrap(),

Use ProgramBuilder::Wrap() in the writers, where we were previously

(especially around AppendVector()).

This is now required as semantic information is generated inside the
writers for newly constructed AST nodes, and we need to register
this semantic info so it can be fetched later.

ProgramBuilder is the mutable builder for Programs, and is not part of

ProgramBuilder.

Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().

Mutable ProgramBuilders can be moved into immutable Programs.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.

As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.

As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.

Ben Clayton 207b5e2de1 Move tint::ast::type to tint::type
Despite `tint::ast::type::Type` being in the AST namespace, these classes are clearly not AST nodes:
* They don't derive from ast::Node
* They're deduplicated by the type manager
* None of the types have an Source - they have no lexical declaration point
* The fact we have `ast::Struct` and `ast::type::Struct` clearly demonstrates what is an AST node, and what is a type.
* We have code scattered in the codebase (TypeDeterminer, writers, etc) that create new types after parsing - so clearly not part of the original syntax tree.

Types in tint are closer to being semantic info, but due to the parse-time generation of types, and tight dependency of ast::Nodes to types, I'd be reluctant to class these as semantic info. Instead, put these into a separate root level `tint::type` namespace and `src/tint` directory.

The fact that types exist in the ast::Module has already caused bugs (https://dawn-review.googlesource.com/c/tint/+/37261). This is a first step in separating out types from the ast::Module.

A container and allocator of objects of (or deriving from) the template type `T`.

Objects are allocated by calling Create(), and are owned by the BlockAllocator.
When the BlockAllocator is destructed, all constructed objects are automatically destructed and freed.

Objects held by the BlockAllocator can be iterated over using a View or ConstView.

Use this to hold the ast::Nodes in the ast::Module

This is called BlockAllocator as it can be optimized to hold objects in contiguous memory blocks, which will improve cache coherencey. Currently BlockAllocator is a straight port of the vector-of-unique-ptr, taken from ast::Module.

Ben Clayton 2bc6840d3c Add ast::CloneContext::ReplaceAll()
ReplaceAll() registers `replacer` to be called whenever the Clone() method is called with a type that matches (or derives from) the type of the first parameter of `replacer`.

`replacer` must be function-like with the signature: `T* (T*)`, where `T` is a type deriving from CastableBase.

If `replacer` returns a nullptr then Clone() will attempt the next registered replacer function that matches the object type. If no replacers match the object type, or all returned nullptr then Clone() will call `T::Clone()` to clone the object.

Example:

```
  // Replace all ast::UintLiterals with the number 42
  CloneCtx ctx(mod);
  ctx.ReplaceAll([&] (ast::UintLiteral* in) {
    return ctx.mod->create<ast::UintLiteral>(ctx.Clone(in->type()), 42);
  });
  auto* out = ctx.Clone(tree);
```

This is to be used by Transforms that want to replace parts of the AST on clone.

Ben Clayton 76d12f0f5a Add EmitVertexPointSizeTransform
EmitVertexPointSizeTransform is a Transformer that adds a PointSize builtin global output variable to the module which is assigned 1.0 as the new first statement for all vertex stage entry points.

If the module does not contain a vertex pipeline stage entry point then then this transformer is a no-op.

Ben Clayton ed2b97811e ast: Add Module.Clone()
Deep-clones all `Node`s and `Type`s into a new module.

Instead of writing a million standalone tests that'll only ever test the
existing fields of each type, I've opted to write the tests using
wgsl<->ast<->wgsl conversion. This means the tests require the enabling
of TINT_BUILD_WGSL_READER and TINT_BUILD_WGSL_WRITER, but I believe this
is much easier to maintain.

I'm aware there are probably gaps in the tests, and that even full
coverage is likely to rapidly rot, so I've also added
fuzzers/tint_ast_clone_fuzzer.cc - a fuzzer based test that ensures that
all AST modules can be cloned with identical reproduction.

I've run this across 100 cores of a 3990x for 4 hours, fixing the
single issue it detected.

Note: Expressions do not currently clone their `TypeManager` determined
types. This is for two reasons:
(a) This initial CL is mahoosive enough.
(b) I'm uncertain whether we actually want to clone this info, or to
    re-run the `TypeDeterminer` after each AST transform. Maybe it should
    be optional. Time will tell.

Ben Clayton 95feb99a9d Add Castable template class
Implements `As<Blah>()` and `Is<Blah>()` automatically.

There are several benefits to using this over the pattern of hand-rolled `IsBlah()`, `AsBlah()` methods:
(1) We don't have to maintain a whole lot of hand written code.
(2) These allow us to cast from the base type to _any_ derived type in a single cast. The existing hand-rolled methods usually require a couple of intermediary casts to go from the base type to the leaf type.
(3) The use of a template parameter means these casts can be called from other template logic.

Note: Unlike the hand-rolled `AsBlah()` methods, it is safe to call `As<T>()` even if the type does not derive from `T`. If the object does not derive from `T` then  `As` will simply return `nullptr`. This allows the calling logic to replace the common pattern of:

```
if (obj.IsBlah()) {
   auto* b = obj.AsBlah();
   ...
}
```

with:

```
if (auto* b = obj.As<Blah>()) {
   ...
}
```

This halves the number of virtual method calls, and is one line shorter.

dan sinclair 5c948e4f8f [transform] Move the transform folder

operate on the AST, but they aren't part of the AST so I think the top

This will possibly cause issues when rolling if the transform is being
used.
