* Make-common (sim_main_headers): Sort.

(cgen-*.o): Add cgen-sim.h dependency.

	* sim-cpu.h: New file.  sim_cpu_base moved here.
	Move sim_cpu_lookup decl here.
	* sim-base.h: #include "sim-cpu.h".
	* sim-cpu.c: New file.
	* Make-common (sim_main_headers): Add sim-cpu.h.
	(sim-cpu.o): Add rule for.
