Antonio Maiorano ab4c035762 tint: fix HLSL countOneBits and reverseBits for i32 args
These two functions in HLSL only accept and return uint. Thus, if the
result of these calls is passed to a function that wants int, it will
fail, or call the uint overload if one exists. Fixed by casting the
result to int if the arg is int.

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.

Ben Clayton 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.

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`.

Stephen White 790e4c2d60 GLSL writer: emit gl_PointSize = 1 in all vertex shaders for OpenGL.
The OpenGL ES 3.1 spec says:

"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."

ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.

This transform converts compound assignment statements into regular

else-if statements if necessary.

The vector-component case needs particular care, as we cannot take the
address of a vector component. We need to capture a pointer to the
whole vector and also the component index expression:

// Before
vector_array[foo()][bar()] *= 2.0;

// After:
let _vec = &vector_array[foo()];
let _idx = bar();
(*_vec)[_idx] = (*_vec)[_idx] * 2.0;

Antonio Maiorano 66d6668372 Implement discard semantics
Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.

Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

Stephen White 66abf3ed14 GLSL: don't emit structs w/runtime-sized arrays.
In GLSL, runtime-sized arrays are only valid in interface blocks, not
in structs. The existing code was attempting to avoid emitting structs
containing runtime-sized arrays but was confused by type aliases in
the AST resulting in arrays being missed.

The fix is to do the work on the semantic types instead, where type
aliases have been resolved.

Unlike other texture functions in GLSL, textureGather() and

refZ to coordinates by default, and pass as a regular parameter only

Stephen White 17601930e4 GLSL: fix textureSampleLevel() on depth textures.
Multiple bugs here:

1) Like texture(), GLSL's textureLod() on depth textures returns a
   scalar, and does not need to be swizzled. So set glsl_ret_width to
   1 in that case.
2) Like texture(), GLSL's textureLod() always requires a Dref
   parameter, so append a zero if not present.
3) GLSL's "lod" parameter to textureLod() is always a float, unlike
   WGSL's textureSampleLevel() which is an i32 for depth textures,
   so cast it.

Along the way, I discovered that textureLod() is not supported on
samplerCubeShadow or sampler2DArrayShadow (even on Desktop GL). So some
tests will never pass. Logged as https://crbug.com/dawn/1313

Ben Clayton 8169693136 builtins: Add firstLeadingBit
Currently polyfilled for all backends.
HLSL should be able to map this to 'firstbithigh', but there might need

just polyfill.
