Replace global IPC with function argument cia or current instruction
...
address.
Pass cia into calls to sim_engine_stop so that breakpoints et.al. work.

IGEN likes to cache the current instruction address (CIA). Change the
...
MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.

Rewrite sim_monitor (implements read, write, open, et.al. system
...
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write. This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
