| | | | | | | | | | | | | | make the output more compact. Divorce state-saving from the doFinalization method; for some reason it's not getting called when I want it to, at Reoptimizer time. Put the guts in PhyRegAlloc::finishSavingState(). Put an abort() in it so that I can be really really sure that it's getting called.
