c5eebaf7d6 sem: Rename methods of sem::Pointer and Reference
Rename:
* type() to StoreType()
* storage_class() to StorageClass()

Move away from snake_case methods in the semantic namespace.
Try to avoid generic 'type()' method names.

Also add an assertion to detect doubly nested references (these are
invalid).

ac90829e1c Create a semantic class for block statements
Semantic information about block statements the resolver would
temporarily create while resolving is now exposed in a
sem::BlockStatement class.

In the process, semantic information about statements in general is
overhauled so that a statement has a reference to its parent
statement, regardless of whether this is a block.

dc4e6c1844 Remove sem::AccessControl
In preparation for implementing
https://github.com/gpuweb/gpuweb/issues/1604, this change removes the
sem::AccessControl node. Instead, the ast::AccessControl::Access enum is
now on the sem::StorageTexture class, as well as on sem::Variable. For
sem::Variable, the field is set when the variable's type is either a
storage buffer or a storage texture.

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.

3103a1f666 BindingRemapper: Allow for binding point collisions
Add a new parameter to BindingRemapper::Remappings that allows resulting binding points to collide.

When enabled, the output of the transform contains two or more module-scoped variables with the same binding point, used by the same entry point, then these variables will be decorated with an internal decoration to disable validation for the collision.

This is to work around collisions generated for the HLSL backend where the variables actually exist in different register classes, which is permitted by D3D12.

The transform will only generate these decorations if it needs to.

02ebf0dcae ast: Migrate to using ast::Type
Remove all sem::Type references from the AST.
ConstructedTypes are now all AST types.

The parsers will still create semantic types, but these are now disjoint
and ignored.
The parsers will be updated with future changes to stop creating these
semantic types.

Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic
information, as semantic nodes are fully rebuilt by the Resolver.

439ef278b7 transform/VertexPulling: Handle entry point parameters
Adds support for the new shader IO syntax by processing entry
parameters and pushing them to function-scope variables as necessary.

Module-scope variables are still supported for now.

73fdc16c33 wgsl parser: replace almost all sem::Type* with typ::Type where possible
All that remains in the wgsl parser that references sem::Type* are
the register_constructed funcs/types, and adding an ast::ExternalTexture
type.

Also:

* Added specialization of OperatorArrow for type::TypePairs that returns
the value by reference so that operator-> can chain properly.

* In a few places where we expect the type to implicitly cast to a
pointer for a bool expression, e.g. `if (type)` or `TINT_ASSERT(type)`,
I added access to the `.sem` member of the TypePair. I tried adding an
implicit cast to bool, but this results in ambiguity in gtest for
equality comparisons.

* Constified more type pointers in type nodes

* Replaced header includes with forward declares in wgsl/parser_impl.h
