Use interval sizes instead of spill weights to determine if it is legal to evict
interference. A smaller interval can evict interference if all interfering live
ranges are larger.

Allow multiple interferences to be evicted as along as they are all larger than
the live range being allocated.

Spill weights are still used to select the preferred eviction candidate.

-In general, don't have the BugReporter deleting BugTypes, BugTypes will eventually become owned by checkers
 and outlive the BugReporter. In the meantime, there will be some leaks since some checkers assume that
 the BugTypes they create will be destroyed by the BugReporter.
-Have BugReporter::EmitBasicReport create BugTypes that are reused if the same name & category strings
 are passed to EmitBasicReport. These BugTypes are owned and destroyed by the BugReporter.
 This allows bugs reported through EmitBasicReport to be coalesced.
-Remove the llvm::FoldingSet<BugReportEquivClass> from BugType and move it into the BugReporter.
 For uniquing BugReportEquivClass also use the BugType* so that we can iterate over all of them using only one set.

This is based on the observation that long live ranges are more difficult to
allocate, so there is a better chance of solving the puzzle by handling the big
pieces first. The allocator will evict and split long alive ranges when they get
in the way.

RABasic is still using spill weights for its priority queue, so the interface to
the queue has been virtualized.
