* mips-tdep.c (MSYMBOL_IS_SPECIAL, MSYMBOL_SIZE): These are only
	used locally, so move them from the target machine header to here.
	(mips_set_processor_type, mips_register_name, mips32_next_pc,
	mips16_next_pc, cached_proc_desc, mips_set_processor_type):
	Make static.
	* config/mips/tm-mips.h (MSYMBOL_IS_SPECIAL, MSYMBOL_SIZE): Delete.
