9c03abfb55 tint: Show the reason for a uniformity requirement
When producing an error from the uniformity analysis, add notes to
show the underlying reason for the uniformity requirement.

For function calls that are required-to-be-uniform, show the innermost
builtin call that has the requirement.

For function parameters that are required-to-be-uniform, recurse into
that function to show where its requirement comes from.

Add some new tests to specifically test the error messages.

874b61f1ba tint/uniformity: Retain control flow graphs
Move the control flow graphs to `FunctionInfo` so that they are not
destroyed when we finish processing the function.

This will make it easier to produce more detailed diagnostics for
uniformity issues, which will be coming in subsequent CLs.

There is no functional change in this CL.

be656f7984 tint: Implement uniformity analaysis
This implements the uniformity analysis as currently described in the
WGSL specification. Uniformity issues are presented as warnings, and
will be switched to errors in a future release.

A follow-up patch will improve the error messages, which currently
just show the point at which a uniformity was detected.

In a future release, once we have obtained initial feedback from
users, uniformity issues will become errors.

keep this change small. In future changes the SPIR-V reader will
produce 'i' suffixed types for these.

Have all consumers of IntLiteralExpression treat unsuffixed integers the

future changes.

`elseif`), and simplifies various pieces of code that handle these

01004b7732 tint: Remove '_type' suffix from file names
These suffixes existed because the GN build errored when there were two files sets with the same name (ast + sem).
This is no longer required as the GN build splits these into two separate targets.

7e8df044c6 tint/writer/spirv: Replace Operand with std::variant
Operand is just a tagged union of uint32_t, float and std::string.

Use std::variant for this.
Reduces memory size, and removes the need to always construct an empty string when the operand is float or int.

617570a7da tint/writer: Replace scope_stack_, fix type ctor scoping.
ScopeStack is not needed here - the resolver already provides variable scoping with the sem::Variables.

Re-purpose scope_stack_ for a stack of Scope, which now holds the type constructor -> SPIR-V ID map.
This map needs to be per-scope, to fix issues like crbug.com/tint/1520

Fixed: tint:1520

e85fe161cd tint: ProgramBuilder: Rename Const() to Let()
These methods produce `let` declarations.
With creation-time expressions, we'll need to add `const` declarations.

Note that module-scope `let` declarations have been removed in the spec (for `const`). ProgramBuilder::GlobalConst() has not been renamed, although it still currently produces 'let' declarations.

046abc08e8 tint/writer: Replace use of strings for cache keys
Concatenating strings to use for cache keys is horribly inefficent and very error prone.

Add a UnorderedKeyWrapper helper to allow types to be used as a unordered_map and unordered_set key. Use this for the type_constructor_to_id_ map.

Produces SPIR-V with some duplicate SPIR-V instructions for constructors removed.

7098d3d692 tint: Add enable directive for extensions
In this CL the enable directive is implemented.
1. Add AST node for enable directive, assign a ExtensionKind (enum) for
each supported extension.
2. Use an unorder_set in ast::Module to record all required extensions'
kind.
3. Provide inspector methods for getting names of used extension, and
getting all used enable directives' extension names and location.
4. For different writer, the extension nodes are handled in different
ways. MSL and HLSL writers will just ignore the extension nodes, while
SPIRV and GLSL writers will emit corresponding code.
5. Implement unittests and end2end test for enable directive and
inspector, using a reserved extension name `InternalExtensionForTesting`.

This PR adds the validator_is_storable test into the CMakeList file
correctly and removes the helper files. The resolver helper is used
instead and a test helper to return the validator added into the
resolver.
