Merge pull request #1847 from KhronosGroup/fix-1775 
Rework how loop iteration counts are validated.

1d13a3e36a Rework how loop iteration counts are validated. 
Introduces an idea of a recompilation making forward progress.

There are some extreme edge cases where we need more than 3 loops, but
only allow this in specific circumstances where we can reason about
forward progress being made.

ef6bde6580 Do not forward expressions which carry a huge amount of dependencies. 
Need to force temporaries eventually, or compilers have a tendency to
explode.

7c12228359 Add sanity test for SPIR-V 1.6 modules. 
Just verify that we don't blow up on these modules.

7c83fc22fa Add support for LocalSizeId. 
WorkgroupSize builtin is deprecated in 1.6 and LocalSizeId is supported
in Vulkan starting with maintenance4.

f1b411c9e8 GLSL: Deal with buffer_reference_align. 
This is somewhat awkward to support, but the best effort we can do here
is to analyze various Load/Store opcodes and deduce the ideal overall
alignment based on this. This is not a 100% perfect solution, but should
be correct for any reasonable use case.

Also fix various nitpicks with BDA support while I'm at it.

CFG: Handle degenerate selection constructs.

2714f5410c CFG: Handle degenerate selection constructs. 
Apparently, it's legal to use a selection construct where both paths
branch to same location, but a different merge point is used.
This breaks many assumptions the variable scope analyzer makes.

The only logical way to generate code for this scenario is to treat the
selection construct as a trivial switch construct with only a default
case.

6071df5840 Fix wrong detection of trivial_mix_op. 
Effectively, only the last component of the select was considered, need
to correctly early out if any case is hit.

f72bb3c6f5 Improve handling of INT_MIN/INT64_MIN literals. 
We cannot naively convert these to decimal literals. C/C++ (and thus
MSL) has extremely awkward literal promotion rules.

Fix bug in to_trivial_mix_op, where we made a pre-1.4 assumption that
component count of selector is equal to value component count.

ee31e84e30 GLSL: Handle complex load/store scenarios to gl_SampleMask. 
Need special workarounds to handle array load/store since array size is
unsized in GLSL, and array copy is not possible.
Also, consider bitcast for scalar loads and stores.
