70ee56c585 Rework sim/common/sim-alu.h to differentiate between direcct
subtraction (involves borrow) and negated addition (involves carry).
Update d30v so that it uses this method.  Add more tests.

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.
