list. This is a bad idea. ;] I'm hopeful this is the bug that's showing up with the MSVC bots, but we'll see. It is definitely unnecessary. InstSimplify won't do anything to a terminator instruction, we don't need to even include it in the iteration range. We can also skip the now dead terminator check, although I've made it an assert to help document that this is an important invariant. I'm still a bit queasy about this because there is an implicit assumption that the terminator instruction cannot be RAUW'ed by the simplification code. While that appears to be true at the moment, I see no guarantee that would ensure it remains true in the future. I'm looking at the cleanest way to solve that... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153399 91177308-0d34-0410-b5e6-96231b3b80d8
