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.

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.

4016e38bea Build: Switch to Rev. 6 of headers, removing "BadValue" enum stuff. 
Note: Technically, this is glslang's modified private copy of official headers.
Official headers will appear in other places, like
https://github.com/KhronosGroup/SPIRV-Headers.

 - AtomicStorage capability

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.

c51287d744 SPV: Update to spec. decisions (and issue #205) for barrier(). 
A barrier (ESSL/GLSL) or OpControlBarrier when in a tessellation control
shader also means doing memory synchronization for output variables.

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

a901ffed40 Defer capability decl for ClipDistance, CullDistance, PointSize until actual use 
The compiler will mark struct members with those builtins, but won't
declare the capability until that member is accessed by some executable
instruction.

Test changes:
- spv.430.vert: was missing ClipDistance capability.
- spv.precise.tese: remove TessellationPointSize capability.

a5c33d6ffb SPV: Fix issue #320: Fetch needs to extract the image. 
GLSL takes a traditional sampler, but SPIR-V wants just the
sampled image, not the combined sampler and image.

bbceed7be3 SPV: Fix an issue of interpolation decoration. 
GLSL interpolation qualifiers and auxiliary storage qualifiers are not
mutually exclusive. So when they are translated to SPIR-V decorations, two
independent utility methods should be employed to do this job.

8d72f1a2c4 Full stack: distinguish between a scalar and a vector of size 1.

This is a fully backward compatible change that allows this distinction.
