991b655c72 Declare OpSpecConstantOp up-front on relevant targets.
Required, since spec constants can include results from constant ops.

7eba247864 Handle inout properly with split access chains.
Found some other issues. Had some bugs with variable writes not properly
invalidating if writes came from split access chains.

40bbf6be7a Build combined dummy samplers for Query functions without sampler as well.
Deal with various query functions which require dummy sampler.
In SPIR-V, separate images are used, but GLSL (even Vulkan GLSL)
requires combined sampler images ...

146ea76f52 Add test shader for subgroup.
Update SPIRV-Tools/glslang commits.
Use vulkan1.1 environment for testing.
Found new "errors" in SPIRV-Tools, so disable validation on those shaders
for now.

e3b8e9455c Add test shader where a phi variable invalidates a temporary.
The temporary in question is used to flush a phi variable.

b3f6e3de8e Fix CFG::update_common_dominator.
The algorithm was too conservative causing lots of unnecessary
temporaries to be created.

09f550f718 Handle exponential explosion of code-gen during first phase of compile.
Certain patterns with OpVectorShuffle (and probably others) will cascade
to so large, that they can cause OOM. After we have observed
force_recompile, don't spend unnecessary memory emitting code which will
never be used.

7d223b8987 Fix CFG for forwarded temporaries.
Forwarded temporaries would never declare a temporary.
Figure out all result types ahead of time so we can deal with those
temporaries as well.

0f4adaa09d Handle OpUnreachable in code-gen.
Forgot to add it to emit_block_chain. It should just be a noop.

d4e470babd Analyze the CFG for temporaries as well.
Normally, temporary declaration must dominate any use of it,
so we generally did not need to analyze the CFG for these variables,
but there is an edge case where you have an inliner doing:

do {
	create_temporary;
	break;
} while(0);

use_temporary;

The inside of the loop dominates the outer scope, but we cannot emit
code like this in GLSL, so make sure we hoist these temporaries outside
the "loop".

9bdfd7025e Fix tessellation control shaders from HLSL.
Need to take into account that gl_Position[i] needs to be rewritten as
gl_out[i].gl_Position instead.

2c90ea3acc Improve handling of block name declaration in GLSL.
HLSL UAVs are a bit annoying because they can share block types,
so reflection becomes rather awkward. Sometimes we will need to make
some nasty fallbacks, so add a reflection interface which lets you query
post-shader compile which names was actually declared in the shader.

0fd028147f Hoist all phi-local variables to entry block.
We don't have a mechanism to move temporaries to their appropriate
scope, and Phi behavior is weird enough that it will be a heroic effort
to not do this rather ugly codegen :(

b629ca1c33 Fix complicated Phi case.
A continue block might have used a temporary which existed only in the
loop body.

8538b4c9c0 Handle empty struct declarations with best effort.
This "feature" is a bit icky as we have no useful representation of it,
so never emit code which has anything to do with empty structs.

656a7ba1d3 Remove irrelevant test.
The UDIV test was testing invalid SPIR-V and recent SPIRV-Tools errors
out on it.
