	mips_generic_reg_names, mips_r3041_reg_names,
	mips_r3051_reg_names, mips_r3081_reg_names,
	mips_processor_type_table): New	globals.
	(mips_do_registers_info): Don't display register if name is empty.
	(mips_set_processor_type_command): New command.
	(mips_show_processor_type_command): New command.
	(mips_set_processor_type): New function.
	(mips_read_processor_type): New function.
	* config/mips/tm-idt.h (DEFAULT_MIPS_TYPE): New macro.
	* config/mips/tm-mips.h (DEFAULT_MIPS_TYPE): New macro.
	(NUM_REGS): Increase to account for all CP0 registers.
	(REGISTER_NAMES): Add empty names for CP0 registers.
	(FIRST_EMBED_REGNUM, LAST_EMBED_REGNUM): Adjust.
	(PRID_REGNUM): New macro.
