* Make-common.in (sim-options.o, sim-load.o): Add rules for.

	(sim_main_headers): Add sim-trace.h.
	* run.c (exec_bfd, target_byte_order): Delete.
	(main): Pass -E <endian> to sim_open.  Delete code to load sections,
	call sim_load instead.  Check return code of sim_create_inferior.
	* sim-base.h (CURRENT_STATE): Define.
	(sim_state_base): Make typedef.  New members options, prog_argv,
	prog_bfd, text_{section,start,end}, start_addr, simcache_size,
	mem_size, memory [+ corresponding access macros].
	(sim_cpu_base): New typedef.
	* sim-trace.h: New file.
	* sim-basics.h: #include it.
	* sim-load.c: New file.
