New Revision: 112220

URL: http://llvm.org/viewvc/llvm-project?rev=112220&view=rev
Log:
Turn off the scavenging based frame reg reuse briefly to measure whether it's
still having a significant effect. It shouldn't be now that the pre-RA
virtual base reg stuff is in. Assuming that's valididated by the nightly
testers, we can simplify a lot of the PEI frame index code.
