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.

a04bdcc7f7 Handle overloaded functions which share the same OpName.
Awkward, but legal SPIR-V.

9fa91f7e1c Support returning arrays from functions in GLSL/MSL.
Not possible in HLSL apparently, need workaround ...

5d9df6a31c Do not declare constant composites inline in HLSL.
Move arrays and structs out to their own global static constants.

Also, replace illegal names in HLSL as well.

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.

HLSL can emit uint here.

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.
