4ba8d09fe2 Change MIPS simulator so that it uses the (software) module sim_fpu 
for floating point operations.  Eliminates all dependencies the
simulator had on the hosts FP implemantation.

Add sim_fpu_{inv,abs,neg} functions to sim_fpu.[hc]

aaa11abe42 Clarify meaning of sim_signalled's SIGRC argument. Document that this 
isn't possible in sim-reason.c and just return the target SIGRC
instead.

For simulators that rely on sim-reason.c, replace SIG* with SIM_SIG*.

Hack nrun.c so that when it is executed (ARGV[0]) as `step' instead
of `run' it single steps the simulator.  Allows testing of single step
without full GDB.
