[PATCH] D22083: Revert "[X86]: Improve Liveness checking for X86FixupBWInsts.cpp"

[Matthias Braun via llvm-commits]

MatzeB added a comment.

I added an assert that the forward liveness analysis would not find additional transformation opportunities. As expected most of the problems were fixed with http://reviews.llvm.org/D22027 in place. However it turned out that there existed another subtle case where forward and backward analysis could disagree, I fixed that one in r274952.
