Ben Clayton 7d34de88f1 tint/test-runner: Split expectations for FXC and DXC
Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.

Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.

Zhaoming Jiang 66d4f6e6fb tint/writer/spirv: Support for F16 type, constructor, and convertor
This patch make SPIRV writer support emitting f16 types, f16 literals,
f16 constructor and convertor. Unittests are also implemented.

Currently SPIRV writer will require 4 capabilities in generated SPIRV:
`Float16`, `UniformAndStorageBuffer16BitAccess`,
`StorageBuffer16BitAccess`, and `storageInputOutput16`.

Zhaoming Jiang 0d3d3210d4 tint/writer/glsl: Support for F16 type, constructor, and convertor
This patch make GLSL writer support emitting f16 types, f16 literals,
f16 constructor and convertor. Unittests are also implemented, and
end-to-end testcases are updated for GLSL extension requirement.

The GLSL writer will require `GL_AMD_gpu_shader_half_float` extension if
f16 WGSL extension is enabled, emit f16 literal as `1.23hf`, and map f16
types as follow:
WGSL type   -> GLSL type
f16         -> float16_t
vec2<f16>   -> f16vec2
vec3<f16>   -> f16vec3
vec4<f16>   -> f16vec4
mat2x2<f16> -> f16mat2
mat2x3<f16> -> f16mat2x3
mat2x4<f16> -> f16mat2x4
mat3x2<f16> -> f16mat3x2
mat3x3<f16> -> f16mat3
mat3x4<f16> -> f16mat3x4
mat4x2<f16> -> f16mat4x2
mat4x3<f16> -> f16mat4x3
mat4x4<f16> -> f16mat4

dan sinclair b29892be09 Update src/tint unittests to new @stage format.
This CL updates all of the Tint unittests to the new @stage shorter
syntax. This also updates the WGSL writer to emit the new short forms
instead of using the deprecated form.

Ben Clayton 7f2b8cd8fc tint: Refactor Extensions / Enables.
* Extract ast::Enable::ExtensionKind to ast::Extension.
* Move the parsing out of ast::Enable and next to ast/extension.h
* Change the ast::Enable constructor to take the Extension, instead of
  a std::string. It's the WGSL parser's responsibility to parse, not the
  AST nodes.
* Add ProgramBuilder::Enable() helper.
* Keep ast::Module simple - keep track of the declared AST Enable nodes,
  don't do any deduplicating of the enabled extensions.
* Add the de-duplicated ast::Extensions to the sem::Module.
* Remove the kInternalExtensionForTesting enum value - we have kF16
  now, which can be used instead for testing.
* Rename kNoExtension to kNone.

Zhaoming Jiang 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`.
