For NEC 4100/4300 project
* gencode.c (build_instruction, case JUMP): Truncate PC to 32 bits.
* interp.c (CHECKHILO): Define away.
(simSIGINT): New macro.
(membank_size): Increase from 1MB to 2MB.
(control_c): New function.
(sim_resume): Rename parameter signal to signal_number. Add local
variable prev. Call signal before and after simulate.
(sim_stop_reason): Add simSIGINT support.
(sim_warning, sim_error, dotrace, SignalException): Define as stdarg
functions always.
(sim_warning): Delete call to SignalException. Do call printf_filtered
if logfh is NULL.
(AddressTranslation): Add #ifdef DEBUG around debugging message and
a call to sim_warning.
