Take execution model into account for entry point methods.

SPIR-V allows names to alias if they implement different stages.
Deprecate the old interface and replace it with a new one which takes
execution modes into account.

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".

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.

We don't have a mechanism to move temporaries to their appropriate

to not do this rather ugly codegen :(
