	syssrc/sys/arch/arm/include/arm32: frame.h

Log 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.
