sh-dsp support, simulator speedup by using host byte order:

(MA, L, TL, TB): Now controlled by ACE_FAST. (SEXT32): Just cast to int. (SIGN32): Fixed to only shift by 31. (CHECK_INSN_PTR): SIGBUS at insn fetch now represented by insn_end 0. (ppi_insn): Declare. (ppi.c): Include. (init_dsp): Set target_dsp. When it changes, switch end of sh_jump_table with sh_dsp_table. (sim_resume) Don't declare sh_jump_table0. Use sh_jump_table instead. Don't Declare PR if it's #defined. Fix single-stepping (Was broken in Mar 6 16:59:10 patch). (sim_store_register, sim_read_register): Translate accesses to reflect saved_state_type change. * interp.c (set_sr): Set sr. (SET_RC, MOD, MOD_MS, MOD_ME, SET_MOD, MOD_MS, MOD_ME): New macros.
