[Nick Desaulniers via Phabricator via llvm-commits]

I'm going to move llvm/test/CodeGen/X86/switch-bit-test-unreachable-default.ll to D109106 <https://reviews.llvm.org/D109106> so that we can also see more easily what's changed by this commit. I'm also going to add a RUN with explicit `-global-isel=0`/`-global-isel=1`.
