* mips.h: Remove documentation of "[" and "]".  Update documentation
	of "k" and the MDMX formats.

opcodes/
	* mips-opc.c (mips_builtin_opcodes): Use "Q" for the INSN_5400
	MDMX-like instructions.
	* mips-dis.c (print_insn_arg): Use "$f" rather than "$v" when
	printing "Q" operands for INSN_5400 instructions.

gas/
	* config/tc-mips.c (validate_mips_insn): Remove "[" and "]" handling.
	(mips_ip): Likewise.  Do not set is_mdmx for INSN_5400 instructions.
	Check constraints on the VR5400 RZU.OB, SLL.OB and SRL.OB instructions.

gas/testsuite/
	* gas/mips/vr5400-ill.s, gas/mips/vr5400-ill.l: New test.
	* gas/mips/mips.exp: Run it.
