intrinsic breakpoints.

SIM_EXITED: The program has terminated. SIGRC indicates the target
dependant exit status.
SIM_STOPPED: The program has stopped. SIGRC indicates the reason:
program interrupted by user via a sim_stop request (SIGINT); a
breakpoint instruction (SIGTRAP); a completed step (SIGTRAP); an
internal error condition (SIGABRT).
SIM_STOPPED: The program has stopped. SIGRC uses the host's signal
numbering as a way of identifying the reaon: program interrupted by
user via a sim_stop request (SIGINT); a breakpoint instruction
(SIGTRAP); a completed single step (SIGTRAP); an internal error
condition (SIGABRT); an illegal instruction (SIGILL); Access to an
undefined memory region (SIGSEGV); Mis-aligned memory access
(SIGBUS).
SIM_SIGNALLED: The simulator encountered target code that requires
the signal SIGRC to be delivered to the simulated program.
