Original commit message:
In cpu_switch(), stack more registers at the start of the function,
and hence save fewer into the PCB. This should give me enough free
registers in cpu_switch to tidy things up and support MULTIPROCESSOR
properly. While we're here, make the stacked registers into an
APCS stack frame, so that DDB backtraces through cpu_switch() will
work.
This also affects cpu_fork(), which has to fabricate a switchframe and
PCB for the new process.
