Dan Gohman c4c550c758 When optimizing for size, don't tail-merge unless it's likely to be a ... code-size win, and not when it's only likely to be code-size neutral, such as when only a single instruction would be eliminated and a new branch would be required. This fixes rdar://7392894. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88692 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-13 21:02:15 +00:00
