17ca0f8f80 Implement SPARCv9 atomic_swap_64 with a pseudo. 
The SWAP instruction only exists in a 32-bit variant, but the 64-bit
atomic swap can be implemented in terms of CASX, like the other atomic
rmw primitives.

c30791627e Implement atomicrmw operations in 32 and 64 bits for SPARCv9. 
These all use the compare-and-swap CASA/CASXA instructions.
