Fix PR404: Loop simplify is really slow on 252.eon This eliminates an N*N*logN algorithm from the loop simplify pass, replacing it with a much simpler and faster alternative. In a debug build, this reduces gccas time on eon from 85s to 42s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14851 91177308-0d34-0410-b5e6-96231b3b80d8
