c03a09c106 writer/hlsl: Rework string printing
Remove `pre` and `out` parameters from most generator methods.
Use the `out_` string stream in TextGenerator, add helpers to TextGenerator to simplify line printing.

Remove the `pre` and `out` fields from TestHelper.

Cleans up the `pre` aspects of the HLSL writer, so the same concept can be used by the MSL writer.
Fixes indentation bugs in formatting.

f6c84e4d45 Use StorageClass::kNone for ast local var decls
To declare a local variable, we write `var name : type`, not `var<function> name : type`.
This change fixes all the places where we were feeding StorageClass::kFunction into variable declarations.

Note that the resolved, semantic variable correctly infers the `kFunction` StorageClass.

b895ba1cea writer/hlsl: Fix all tests that had unreachable AST nodes
By making nodes reachable, the resolver has now caught a whole lot of additional problems, which have been fixed in this CL.

Some of these broken tests were attempting to use private and workgroup variables as function-scope declarations.
This is not legal, and these have been moved to module-scope variables.

ab26a8fd34 hlsl/writer: Transpose matrices
HLSL's matrices are declared as <type>NxM, where N is the number of
rows and M is the number of columns. Despite HLSL's matrices being
column-major by default, the index operator and constructors actually
operate on row-vectors, where as WGSL operates on column vectors.
To simplify everything we use the transpose of the matrices.

This is the same approach taken by SPIRV-Cross.

9ef17472e8 Add semantic::Variable::Type() and use it instead of ast::Variable::type()
In anticipation of adding support for type inference, no longer use
ast::Variable::type() everywhere, as it will eventually return nullptr
for type-inferred variables. Instead, the Resolver now stores the final
resolved type into the semantic::Variable, and nearly all code now makes
use of that.

ast::Variable::type() has been renamed to ast::Variable::declared_type()
to help make its usage clear, and to distinguish it from
semantic::Variable::Type().

Fixed tests that failed after this change because variables were missing
VariableDeclStatements, so there was no path to the variables during
resolving, and thus no semantic info generated for them.

be0fc4e929 Validate binary operations
This change validates that the operand types and result type of every
binary operation is valid.

* Added two unit tests which test all valid and invalid param combos. I
also removed the old tests, many of which failed once I added this
validation, and the rest are obviated by the new tests.

* Fixed VertexPulling transform, as well as many tests, that were using
invalid operand types for binary operations.

StructMember, Type, Variable), such that all *Decoration classes now

validator.

5b36d2c612 Remove all unnecessary includes
All includes from .cc to .h are preserved, even when transitively included.

It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.

There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

semantic::Call derives from semantic::Expression, and Type() is the return type of the function
Pull the mutable semantic field from ast::Identifier and into a new semantic nodes.
Have the TypeDeterminer create these new semantic nodes.

Note: This change also fixes the node that holds the semantic information for a call.
Previously this was on the identifier, and this is now correctly on the CallExpression.
The identifier of the CallExpression should resolve to the target function, not the return type.
Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.

401b96b9bb Simplify usage of the TypeDeterminer in tests
Make private all TypeDeterminer::DetermineXXX() methods, forcing all tests to use the root-level TypeDeterminer::Determine() method.
Remove TypeDeterminer::RegisterVariableForTesting().

The main use for calling the TypeDeterminer::DetermineXXX() methods was to perform type determination on a partial AST.
This was messy and often resulting in multiple calls into TypeDeterminer. Most tests already perform a full TypeDeterminer::Determine() call when the program is built, so many of these were redundant.
The exposure of these internal methods for testing also makes refactoring the TypeDeterminer extremely difficult.

Add a number of ProgramBuilder helper methods for attaching the partial AST in these tests to the root of the AST, greatly simplifying the use of the TypeDeterminer:
* ProgramBuilder::Global() and ProgramBuilder::GlobalConst() are helpers that register the variable returned by ProgramBuilder::Var() and ProgramBuilder::Const(), respectively.
* ProgramBuilder::WrapInFunction() is a variadic function that accepts variables, expressions and statements, attaching these to the root of the AST via a dummy function.

Most test classes now no longer use their own TypeDeterminer, and instead properly depend on the automatic type determination performed at Program build time.

c40f627bea Migrate from using ast::Module to Program
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.

Depends on https://dawn-review.googlesource.com/c/dawn/+/38522

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.

f1b0e1ee57 ast/type: Remove Type suffix from all types

2da833d815 writer: Simplify floats when printed
Add `tint::writer::FloatToString()`:

Converts the float `f` to a string using fixed-point notation (not scientific).
The float will be printed with the full precision required to describe the float.
All trailing `0`s will be omitted after the last non-zero fractional number,
unless the fractional is zero, in which case the number will end with `.0`.

Use this for the wgsl, msl and hlsl backends.

d2f73226bc [hlsl-writer] Use mul method where required.
This CL updates the binary operator emission to use the `mul()` method
in the following cases:
 - vector * matrix
 - matrix * vector
 - matrix * matrix

This is because the `*` operator works per-component in HLSL which does
not do the expected multiply.

4bfe461646 Big cleanup now that AST nodes are raw pointers
Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
    readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
    they can be repopulated and used again. This is undefined behavior:

> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.

All of these UB cases have been fixed.

Removed all duplicate variables left over from:
  `auto* foo_ptr = foo.get()`
which became:
  `auto* foo_ptr = foo`

b29b09fba6 ast: Add body parameter to ast::Function constructors
In a near-future change, AST nodes, such as ast::BlockStatement will no longer
be std::unique_ptrs, and will have to be constructed and owned by an external
class. This means AST nodes can no longer allocate default child nodes.
