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.

Handle OpUnreachable in code-gen.
...
Forgot to add it to emit_block_chain. It should just be a noop.

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".
