PrologEpilogInserter.cpp
Hi Lauro,
This is the wrong fix.
Even if disabling the use of RS when FP is used is correct, that's up
to the target to not instantiate RS when it detects that. PEI
shouldn't do this check. Please revert this fix. I'm going to reopen
the bug because we need a proper fix.

I'm not disabling the use of RS when FP is used. About 30 lines before my
change, there is this code:
if (RS RegInfo-hasFP(Fn)) {
int SFI = RS-getScavengingFrameIndex();
if (SFI = 0) {
...
The bug was: the PrologEpilogInserter has two chunks of code to define the
ScavengingFrameIndex
