	* alpha-opc.h (alpha_insn_set): VAX floating point opcode was
 	incorrectly defined as 0x16 when it should be 0x15.
	(FLOAT_FORMAT_MASK): function code is 11 bits, not just 7 bits!
	(alpha_insn_set): added cvtst and cvttq float ops.  Also added
 	excb (exception barrier) which is defined in the Alpha
 	Architecture Handbook version 2.
	* alpha-dis.c (print_insn_alpha): Fixed special-case decoding for
 	OPERATE_FORMAT_CODE type instructions.  The bug caused mulq to be
 	disassembled as or, for example.
