* Remove the -stopraise option, which is no longer needed now that we have
the -debug-pass=Arguments option * Run instcombining BEFORE mem2reg so that getelementptr X, long 0's are cleaned up. This is also important because scalar replacement of aggr. will want instcombine to run before it goes as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3879 91177308-0d34-0410-b5e6-96231b3b80d8
