elfread.c (elf_symtab_read): merge SYMBOL_IS_SPECIAL into MAKE_MSYMBOL_SPECIAL

config/mips/tm-mips.h: ditto
symtab.h: update comments re minimal_symbol->info
mips-tdep.c: globalize gdb_print_insn_mips
txvu-tdep.c: disassemble support
config/mips/tm-txvu.h: add vu_pc, use MAKE_MSYMBOL_SPECIAL, track updates
	from tm-r5900.h
