Improvements over r195317: - Set/restore EnableFastISel flag instead of just running FastISel within SelectAllBasicBlocks; the flag is checked in various places, and FastISel won't run properly if those places don't do the right thing. - Test looks for normal ISel versus FastISel behavior, and not something more subtle that doesn't work everywhere. Based on work by Andrea Di Biagio. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195491 91177308-0d34-0410-b5e6-96231b3b80d8
