Now that %ebx is not fixed anymore, we can always use it and avoid all PIC related complications in atomic_compare_and_swap_doubleword pattern. Attached patch fixes sync/atomic on CentOS 5 and doesn't regress in Fedora 20. The patch in effect reverts Ian's patch at [1].

This also eliminates the fsca pattern changes in the previous patch. Since the 'fpu_switch' insn is still a multiple set insn, it won't be used for delay slot stuffing, but this is a minor issue that can be addressed later. I'm testing the patch now on sh-sim. At least 'make all' works.
