Ben Clayton e6e96def66 tint: Add operator support to intrinsic-gen
Adapt the builtin parsing and resolving to also support operators.
Will be used to generate intrinsic table entries for operators.

This will simplify maintenance of the operators, and will greatly
simplify the [AbstractInt -> i32|u32] [AbstractFloat -> f32|f16] logic.

Ben Clayton e132516e6f tint: Rename and move builtin_table and builtin-gen
• Rename 'builtin-gen' back to 'intrinsic-gen', as 'intrinsics' now
  include both builtins and operators.
• Move the intrinsic definitions, and IntrinsicTable to the resolver
  package, where it belongs.

Ben Clayton 0ce9ab042e tint: Change all ProgramBuilder literals to 'i' or 'u' suffix
Unsuffixed integer literals are currently treated as i32,
but will shortly become AbstractInteger. To keep tests behaving
identically to how they are currently, change all test literals
to using either 'i' or 'u' suffixes.

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.

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.

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

Brandon Jones 6661b28d1e Delete Single-Plane External Texture Transform
The multiplanar external texture transform has been integrated into
Dawn, which means we have no use for the single plane transform - so it
should be deleted.

Ben Clayton 8169693136 builtins: Add firstLeadingBit
Currently polyfilled for all backends.
HLSL should be able to map this to 'firstbithigh', but there might need
to be some special case handling for 0 (undocumented behavior). For now
just polyfill.
