First cut at atomics for 64-bit machines and SMP machines.

# Note: Cavium provided a port that has atomics similar to these, but
# that does a syncw; sync; atomic; sync; syncw where we just do the classic
# mips 'atomic' operation (eg ll; frob; sc).  It is unclear to me why
# the extra is needed.  Since my initial target is one core, I'll defer
# investigation until I bring up multiple cores.  syncw is an octeon specific
# instruction.
