* vu0.h: New file with cop2/vu0 instructions.

Browse Source 
* mips-opc.c: Include vu0.h.
        * mips-dis.c (print_insn_arg): Handle new args 0-9, +, -, %, K, &,
        J, Q, X, and U.
        (print_insn_mips): Do not emit a tab after an instruction if the
        first arg is an instruction completer (&).  If the next arg is an
        escape character (%), then print the next arg verbatim.
        * Makefile.am (mips-opc.lo): Depend on vu0.h
