Dlp-version: 11.0.200.100

Intel has disclosed a set of new instructions for Tremont processor.
The spec is

	* testsuite/gas/i386/x86-64-movdir64b-reg.l: Likewise.

opcodes/
	* i386-dis.c (enum): Add PREFIX_0F38F8, PREFIX_0F38F9,
	MOD_0F38F8_PREFIX_2, MOD_0F38F9_PREFIX_0.
	(prefix_table): New instructions (see prefix above).
	(mod_table): New instructions (see prefix above).
	Add Gva macro and handling in OP_G.
	* i386-gen.c (cpu_flag_init): Add CPU_MOVDIRI_FLAGS,
	CPU_MOVDIR64B_FLAGS.
	(cpu_flags): Likewise.
	(opcode_modifiers): Add AddrPrefixOpReg.
	(i386_opcode_modifier): Likewise.
	* i386-opc.h (enum): Add CpuMOVDIRI, CpuMOVDIR64B.
	(i386_cpu_flags): Likewise.
	* i386-opc.tbl: Add movidir{i,64b}.
