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".

Bug: OpLoad fails when loading an interface struct directly, followed by
OpCompositeExtract. This should be fixed, but not critical enough to
block this PR.
