This removes implicit assumption about the form of MI coming into regalloc. In particular, it should be independent of ProcessImplicitDefs which will eventually become a standard part of coming out of SSA--unless we simply can eliminate IMPLICIT_DEF completely. Current unit tests expose this once I remove incidental pass ordering restrictions. This is not a final fix. Just a temporary workaround until I figure out the right way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149360 91177308-0d34-0410-b5e6-96231b3b80d8
