Bob Wilson	82d5534acc	Delete dead PHI machine instructions. These can be created due to type ... legalization even when the IR-level optimizer has removed dead phis, such as when the high half of an i64 value is unused on a 32-bit target. I had to adjust a few test cases that had dead phis. This is a partial fix for Radar 7627077. llvm-svn: 95816	2010-02-10 22:58:57 +00:00
