This reverts commits r272797 and r272835.

I believe the improvements of these commits are merely workarounds for the
broken behaviour of the BranchFolder which I believe to have fixed in
http://reviews.llvm.org/D22027, so this should no longer be necessary.

The goal here is to make codegen independent of the presence of kill
flags which means we have to avoid LivePhysRegs::stepForward() calls
(among other things).
