[PATCH] Provide the register scavenger to processFunctionBeforeFrameFinalized

[Hal Finkel]

Hello again,

Please review this patch which adds 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. This is part of a set of improvements to the PowerPC spill-code handling.

Thanks again,
Hal
