Chandler Carruth 33ae899113 Merge the removal of dead instructions and lifetime markers with the analysis of the alloca. We don't need to visit all the users twice for this. We build up a kill list during the analysis and then just process it afterward. This recovers the tiny bit of performance lost by moving to the visitor based analysis system as it removes one entire use-list walk from mem2reg. In some cases, this is now faster than mem2reg was previously. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187296 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-27 09:43:30 +00:00
