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 ...

294259e2f1 Fix type aliasing on MSL.
Be careful about who gets to be the alias master, and don't alias types
when we have packed types in play.

eecbeaa33d Take execution model into account for entry point methods.
SPIR-V allows names to alias if they implement different stages.
Deprecate the old interface and replace it with a new one which takes
execution modes into account.

dd603eab58 Support spec constant array size in blocks.
Won't really be correct if the spec constant is changed outside
SPIRV-Cross, but nothing we can do about that, really.

4a7a37256e Check if a loop variable candidate is actually used.
Phi nodes used in continue blocks are not always loop variables.
Fix by checking if path from dominator to loop header has some variable
use.

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.

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".

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.
