[PATCH] Fix PR target/26272 __builtin_setjmp and loops on powerpc-darwin

Subject: [PATCH] Fix PR target/26272 __builtin_setjmp and loops on powerpc-darwin

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? Bootstrapped and tested on powerpc-darwin.

A similar fix for x86-darwin will be needed but I cannot test it.

Thanks,
Andrew Pinski

ChangeLog:
	* config/rs6000/darwin.md (load_macho_picbase_si): Add
	pc to the pattern.
	(load_macho_picbase_di): Likewise.
