ef94b1a5ca Fix dref explicit LOD form of sample with cube texture arrays 
The dref parameter was being used as the LOD.  Now it it's properly the dref.

735d7e56a6 Address part A of #982: $Global will use std140 instead of HLSL offsets. 
From comment about this:
Adjust alignment for HLSL rules
TODO: make this consistent in early phases of code: adjusting this late means inconsistencies with earlier code, which for reflection is an issue.
Until reflection is brought in sync with these adjustments, don't apply to $Global,
which is the most likely to rely on reflection, and least likely to rely
implicit layouts.

cabbb788b4 Implement extension GL_AMD_gpu_shader_int16 
- Add int16 types (int16_t, uint16_t, i16vec, u16vec).
- Add int16 support to GLSL operators.
- Add int16 type conversions (to int16, from int16).
- Add int16 built-in functions.

7cdf3fc3c6 Replace #422: Remove the redundant location setting in AST->SPIR-V. 
This was redundant in two ways:
1) it replicated algorithms owned in the front end, and
2) it sometimes left location information on both a block and its members.

0d2b4713c5 HLSL: Don't do logical short-circuits when the operands are bool-vectors. 
This seems a bit ill-defined, and was generating code that made OpPhi of two
operands that were Boolean vectors result in a scalar bool.

f1709e7146 HLSL: implement [unroll] and [loop] attributes 
This adds infrastructure suitable for any front end to create SPIR-V loop
control flags.  The only current front end doing so is HLSL.

[unroll] turns into spv::LoopControlUnrollMask
[loop] turns into spv::LoopControlDontUnrollMask
no specification means spv::LoopControlMaskNone

Corresponds to the EShMsgHlslOffsets flag in messages.

e741249b72 HLSL: pass tessellation execution modes through to SPIR-V 
The SPIR-V generator had assumed tessellation modes such as
primitive type and vertex order would only appear in tess eval
(domain) shaders.  SPIR-V allows either, and HLSL allows and
possibly requires them to be in the hull shader.

This change:

1. Passes them through for either tessellation stage, and,

2. Does not set up defaults in the domain stage for HLSl compilation,
to avoid conflicting definitions.
