  [InstCombine] fix another poison-unsafe select transformation

This fixes another unsafe select folding by disabling it if
EnableUnsafeSelectTransform is set to false.

EnableUnsafeSelectTransform's default value is true, hence it won't
affect generated code (unless the flag is explicitly set to false).
