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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95816 91177308-0d34-0410-b5e6-96231b3b80d8
