Fix some nondeterminstic behavior in the mem2reg pass that (in addition to nondeterminism being bad) could cause some trivial missed optimizations (dead phi nodes being left around for later passes to clean up). With this, llvm-gcc4 now bootstraps and correctly compares. I don't know why I never tried to do it before... :) llvm-svn: 27984
