4ad6c160a5 Precompute interference for neighbor blocks as long as there is no interference. 
This doesn't require seeking in the live interval union, so it is very cheap.

91cbcaf957 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.
