Ok, I'm withdrawing the save_gprs changes (and the change to special case
%r15 for .cfi_restore).  For global regs I'd say .cfi_restore does no harm,
but could be omitted, but we shouldn't be having .cfi_offset in the prologue
for them either.
I started testing the patch today and even with %r15 handled as was before
e.g. cleanup-9.c hangs, so I'll need to debug what is actually going on...
