[LoopDeletion] NFC: Move phi node value setting into prepass Currently, the implementation of delete dead loops has a special case when the loop being deleted is never executed. This special case (updating of exit block's incoming values for phis) can be run as a prepass for non-executable loops before performing the actual deletion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@306157 91177308-0d34-0410-b5e6-96231b3b80d8
