  Log Message:
  -----------
  [SimplifyCFG] Prohibit hoisting of llvm.deoptimize calls

This prohibits hoisiting identical llvm.deoptimize calls
from 'then' and 'else' blocks of a conditional branch.
This fixes a crash that happened because we didn't hoist
the return instructions together with the llvm.deoptimize calls,
so the verifier would crash.
