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.

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.

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.

a4fafa0607 Fix edge-case where do/while body is a dominator. 
Shows up quite a lot in inlined code, should get more test coverage in
this area ...

ad2b7c05e7 Implement workaround for textureLod on 2D array shadow. 
This does not exist in GLSL, but it exists in HLSL if LOD == 0.0.

706d3ead29 Always run spirv-val for SPIR-V files created.

042475e88e Add support for multiple entry points. 
- Only consider I/O variables if part of OpEntryPoint.
- Keep a safe fallback if #entry-points is 1 to avoid potentially
  breaking previously working shaders.

36a0b63f28 Fix various corner cases with expression dependencies. 
There was a potential problem if variables were invalidated and SPIR-V
read expressions which depended on other expression which in turn depended on the
invalidated variable.

Also fixes issue where variables were considered immutable if they were
forwardable. This allowed some incorrect optimizations to slip through.

6aa2007cba Deal better with OpName and OpMemberName which alias. 
OpName is only for debug information, so we must be very careful that
we do not reuse the same name for different variables.

This was previously done for local variables, but this commit extends
this to global variables as well.

45ad58a903 Implement more correct integer op handling. 
In some cases we need to bitcast when dealing with int vs. uint.
SPIR-V allows inputs to be of different integer signedness, so we need
to deal with this somehow.

Add testing system to test SPIR-V assembly.
For now, test all possible combination for all major cases.

 - IAdd (which doesn't care about input type as long as they're equal)
 - SDiv/UDiv operations which case about input type.
 - Arith/Logical right shifts.
 - IEqual to test outputs to bvec, which shouldn't get output cast. Also
   tests casting in function-like calls.
