	* config/tc-i386.c (check_prefix): New static function, split out
	from md_assemble.
	(struct _i386_insn): Add wait_prefix field.
	(md_assemble): Remove wait_prefix local variable.  Use
	check_prefix when adding a prefix.

	* config/tc-i386.c (current_templates): New static variable.
	(md_assemble): Remove current_templates local variable.
	(md_assemble, i386_operand): Improve error and warning messages in
	many places.  Add RESTORE_END_STRING in many places before error
	return.  Clarify some comments.

	* config/tc-i386.c (struct _i386_insn): Change seg field to a two
	element array.
	(md_assemble): Parse string instruction operands, looking for
	segment override prefixes.  Check for invalid segment prefixes on
	string instruction.
	(i386_operand): i.seg[] and max mem_operand changes for string
	insns.
	* config/tc-i386.h (EsSeg): Define.

	* config/tc-i386.h (regKludge): Define.
	(iclrKludge, imulKludge): Don't define.
	* config/tc-i386.c (md_assemble): Merge imulKludge and iclrKludge
	code.  Move ReverseRegRegmem fudges into Modrm case.  Reorder
	opcode_modifier checks to look for more common cases first.  Add
	default_seg for IsString case.
