Fix PR9883. Make sure all caches are invalidated when a live range is repaired.
The previous invalidation missed the alias interference caches. Also add a stats counter for the number of repaired ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131133 91177308-0d34-0410-b5e6-96231b3b80d8
