CFG: Handle degenerate selection constructs.

2714f5410c CFG: Handle degenerate selection constructs.
Apparently, it's legal to use a selection construct where both paths
branch to same location, but a different merge point is used.
This breaks many assumptions the variable scope analyzer makes.

The only logical way to generate code for this scenario is to treat the
selection construct as a trivial switch construct with only a default
case.

4561ecddbd Handle Modf/Frexp in more cases.
Consider it a write to a variable, similar to OpStore.

6071df5840 Fix wrong detection of trivial_mix_op.
Effectively, only the last component of the select was considered, need
to correctly early out if any case is hit.

f72bb3c6f5 Improve handling of INT_MIN/INT64_MIN literals.
We cannot naively convert these to decimal literals. C/C++ (and thus
MSL) has extremely awkward literal promotion rules.

Fix bug in to_trivial_mix_op, where we made a pre-1.4 assumption that
component count of selector is equal to value component count.

ee31e84e30 GLSL: Handle complex load/store scenarios to gl_SampleMask.
Need special workarounds to handle array load/store since array size is
unsized in GLSL, and array copy is not possible.
Also, consider bitcast for scalar loads and stores.

6a614cc7f7 Normalize all internal workaround methods to use spv prefix.
We have been interchanging spv and SPIRV_Cross_ for a while, which
causes weirdness since we don't explicitly ban SPIRV_Cross identifiers,
as these identifiers are generally used for interface variable
workarounds.
