I haven't tested it yet (waiting on some updates from colleagues here)
but there should be no time increase.  Quite literally, it just involves
moving member functions from one class to another, creating a new pass
and adding in the proper AnalysisUsage information.

Separating out the spill cost computation will increase compile time
but I don't imagine it will be significant.
