o Provide poll_quit callback to simulators
so that they can poll for SIGINT on
clueless OS's.
o Add sim_stop to simulators so that clients
can request a halt (eg gdbtk's STOP button)
Works for PPC!
o Re-arange remote-sim.c so that the
hard work is moved from gdbsim_resume()
to gdbsim_wait() (where it should be).

specify the alignment restrictions of the target architecture -
without this option all alignment restrictions are accomodated.

function call convention.

(ONOT): Define.
(sim_resume, shift/rotate cases): Add support for shift/rotate
by two bits.
(OSHIFTS): Corresponding changes.
Handling more H8/S ops.
of holding them in "abs". Handle ABS8MEM memory references aka
8-bit area. Replace ABSMOV references with ABS8MEM.
So we've got a chance of simulating something like btst #0,@40:8 correctly.
