This doesn't require seeking in the live interval union, so it is very cheap.

Add an InterferenceCache class for caching per-block interference ranges. · 91cbcaf9

Jakob Stoklund Olesen authored Apr 02, 2011

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.
