Merge pull request #408 from KhronosGroup/fix-407 
Check if a loop variable candidate is actually used.

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.

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.
