  Modified files:
    sys/sparc64/sparc64  swtch.S 
  Log:
  - Generally improve register usage in cpu_switch.  Use the 'in' registers
    for temporaries relating to the state of the new process instead of the
    outs, so that functions can be called without fear of clobbering them.
  - Use savefpctx instead of rolling our own.
