Add LiveInterval::RenumberValues - Garbage collection for VNInfos.
After heavy editing of a live interval, it is much easier to simply renumber the live values instead of trying to keep track of the unused ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110463 91177308-0d34-0410-b5e6-96231b3b80d8
