bfe6f50b8e Remove cfg_analysis option. 
Not using this is broken, and won't work anymore.

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".

1a5a755ce5 Flatten structs based on instance name rather than block name. 
Block name is too brittle, optimizes will merge block types, making
flattening impossible with unique names.

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 :(
