[SPIR-V] Don't change switch condition type in CodeGen opts (#94959)
This change makes sure the preferred switch condition int type size
remains the same throughout CodeGen optimizations.
The change fixes running several OpenCL applications with -O2 or higher
opt levels, and fixes Basic/stream/stream_max_stmt_exceed.cpp DPC++ E2E
test with -O2.
