The problem here is that the patters for the reloading of the PIC register is being moved before the loop and before the actual setjmp. This causes gcc.c-torture/execute/built-in-setjmp.c to fail at -O2 and above.
This fixes the problem by adding (pc) so that move loop invariants
don't move the reloading of the PIC register before the loop.
OK?

Ok. I'll pre-approve the x86 version, if you'd like to do that one as well. I think the x86 patch would be fine with little testing. There is lots that remains to be done there anyway.
