23946b3606 tint: Move Switch() to own header
castable.h is bigger than it needs to be, and pretty much every tint .cc file includes castable.h
Reduce the amount of code that .cc files that don't use Switch() need to compile.

9543f74739 Move sem::BuiltinType to builtin::Function.
This CL moves `sem::BuiltinType` to `builtin::Function`. This makes it
available for use in the IR. The `Function` name better maps to the
usage in that it contains the builtin functions.

971318f7a2 tint: Replace all remaining AST types with ast::Type
This CL removes the following AST nodes:
* ast::Array
* ast::Atomic
* ast::Matrix
* ast::MultisampledTexture
* ast::Pointer
* ast::SampledTexture
* ast::Texture
* ast::TypeName
* ast::Vector

ast::Type, which used to be the base class for all AST types, is now a
thin wrapper around ast::IdentifierExpression. All types are now
referred to using their type name.

The resolver now handles type resolution and validation of the types
listed above based on the TemplateIdentifier arguments.

Other changes:
* ProgramBuilder has undergone substantial refactoring.
* ProgramBuilder helpers for type inferencing is now more explicit.
  Instead of passing 'nullptr', a new 'Infer' template argument is
  passed.
* ast::CheckIdentifier() is used for more tests that check identifiers,
  including types.

857b1580c7 tint/uniformity: Handle pointer uniformity
This change is a necessary to support workgroupUniformLoad in a
following patch. Otherwise, there is no change to the set of shaders
that are accepted or rejected by the analysis.

We now distinguish between uniformity requirements on the contents of
a pointer parameter versus the pointer value itself when generating
tags for function parameters.

Whilst processing an expression, if we see a sem::Load node we pass a
flag down through child expressions to indicate that we will be
loading from the result. When processing an identifier expression, we
can then select between adding an edge to the source of the
pointer/reference versus the contents of the root identifier that it
corresponds to.

Since the pointers passed to atomic builtins can be uniform, we
special-case them to capture the fact that their return value is
always considered non-uniform.

The arrayLength builtin no longer needs special-casing.

Added many tests to cover various cases that are now captured
differently in the graph. There are two cases that are disabled as
they require variable pointers to trigger the uniformity violation.

2f9a98870e tint: Implement sem::Load
The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().

The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.

Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.

There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.
