Caio Marcelo de Oliveira Filho aaee162781 spirv: Fix handling of OpBranchConditional with same THEN and ELSE
When an OpBranchConditional that had two equal branches was parsed, we
were treating it as a regular OpBranch.  However this doesn't work
well when there's an associated OpSelectionMerge.  We ended up
skipping marking the merge block as such, and depending on what was
inside the construct we would end up trying to process the block
twice.

Fix this by keeping the vtn_if around, but when emitting NIR identify
the two equal branch case.

Fixes: 9c2a11430e ("spirv: Rewrite CFG construction")
Closes: #3786, #4580
