Add the current PEI register scavenger as a parameter to the processFunctionBeforeFrameFinalized callback. This change is necessary in order to allow the PowerPC target code to set the register scavenger frame index after the save-area offset adjustments performed by processFunctionBeforeFrameFinalized. Only after these adjustments have been made is it possible to estimate the size of the stack frame. llvm-svn: 177108
