Add an InterferenceCache class for caching per-block interference ranges. When the greedy register allocator is splitting multiple global live ranges, it tends to look at the same interference data many times. The InterferenceCache class caches queries for unaltered LiveIntervalUnions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128764 91177308-0d34-0410-b5e6-96231b3b80d8
