If any def of a machine-sink candidate has local uses, it's obviously not safe to sink it to a successor block. This bug has been hidden because a later check for critical-edge disable these illegal optimizations. This patch should significantly reduce the amount of time spent on checking dominator information for obviously unsafe sinking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111450 91177308-0d34-0410-b5e6-96231b3b80d8
