I see that mips_push_dummy_frame saves the state of the FP
registers, but mips_pop_frame does not appear to restore them.
Is there any reason for that? It restores FPCSR, but not the
FP regs themselves.
This of course causes about 5 fails in callfuncs.exp, when
we try to make sure that the registers are unchanged accross
a target function call.

Oops, I'm mistaken -- never mind.
