Dan Gohman 5022dd9cc9 Make tail merging handle blocks with repeated predecessors correctly, and ... remove RemoveDuplicateSuccessor, as it is no longer necessary, and because it breaks assumptions made in MachineBasicBlock::isOnlyReachableByFallthrough. Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase for PR4732. test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to it being bugpoint-reduced to the point where it doesn't matter what the condition for the branch is. Add some more interesting code to test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase that originally motivated the RemoveDuplicateSuccessor code, to help verify that the original problem isn't being re-broken. llvm-svn: 79338		2009-08-18 15:18:18 +00:00
