c9e3c3c941 Parser: Implement extension GL_AMD_gpu_shader_half_float. 
- Add built-in types: float16_t, f16vec, f16mat.
- Add support of half float constant: hf, HF.
- Extend built-in floating-point operators: +, -, *, /, ++, --, +=, -=,
  *=, /=, ==, !=, >=, <=, >, <.
- Add support of type conversions: float16_t -> XXX, XXX -> float16_t.

04b3e8746f SPV: PrimitiveId in frag shader will emit Geometry capability 
Using PrimitiveId in a fragment shader requires declaring
an OpCapability with either Geometry or Tessellation.

4bf7155051 SPV: Flatten structs for copy when they are GLSL type aliases. 
Addresses issue #304 and issue #307 by replacing unmatched type OpStores with
per-member copies. Covers assignment statements and most argument passing, but
does not yet cover r-value-based argument passing.

f2b7f3353b SPV: Tighten up number of struct-types declared based on decoration. 
Takes some pressure off of issue #304.
Structures don't inherit locations and then explicitly decorate
members with them, so removed this reason to have another instance
of a structure type.

b86e8b629a Revert "Merge pull request #456 from steve-lunarg/remapper-literal64" 
This reverts commit ad08b30f696267ec6243dd0ad68a3db889cd2d21, reversing
changes made to 28660bb580d4c61e16ef75008550a87b3be90b91.

This backs out the pull request
https://github.com/KhronosGroup/glslang/pull/456 because it introduced
several internal errors even on code that only uses 32-bit numeric
types.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation. 
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

8c8505c604 SPV: For AST interpolateAt* ops consuming a swizzle, invert the order. 
Apply the interpolation first, then apply the swizzle to the result,
the inverse of the order requested by the AST.  This fixes issue #411.

65336488a8 SPV: projective texturing: move the project coordinate. 
SPV doesn't allow gaps in the components of the texturing coordinate.
It also removes the shadow reference.
So, close up the components so all used components are together.

ed15ef1a5b GlslangToSpv: Pass the pointer directly into the client function for opaque types 
For opaque types such as samplers, images, and atomic counters, we want to
reference the actual object in the child function.  For a long time, we
used a shadow variable and made a copy of the image/sampler.  In 76d0ac1a,
this was changed to not shadow samplers.  However, this didn't cover all
opaque types and it also didn't get the pointer storage classes right.
This commit fixes both of these issues.

Fixes #324
