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.

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 93f686617e GLSL: fix textureGather() and textureGatherOffset() with depth textures. 
Unlike other texture functions in GLSL, textureGather() and
textureGatherOffset() do not expect the refZ value to be appended to
the texture coordinates. It is passed as a regular argument. So append
refZ to coordinates by default, and pass as a regular parameter only
for the gather functions.
