* Makefile.in (psim.o): Now that inlines are turned on, make
psim.o depend on all sources.
* cpu.c (cpu_add_commas): New function to format a long with
commas.
(cpu_print_info): Use it to print number_of_insns.
* ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
2, 4, and 8 bytes.
(ENDIAN_N): If both target and host byte orders are known, don't
