Looking at this a bit more, I'm not sure that just short-circuiting
actually covers all the cases. Unfortunately, we don't know what all the
cases are because the SPIR-V spec doesn't say. I'm trying to work towards
fixing that right now.

I'd say it is legal. The spec does not mandate that each branch has its own
merge instruction; only that the control flow must be structured for shaders.
In
Woah, is this legal SPIR-V? I think a second OpSelectionMerge is required.

This fixes the case when the SPIR-V code has two nested conditional
branches, but only one selection merge:

%1 = OpLabel
