Log message:
	The VGATHER group of instructions requires that all three involved
	xmm/ymm registers are distinct. This patch adds code to check for this,
	and at once eliminates a superfluous check for not using PC-relative
	addressing for these instructions (the fact that an index register is
	required here already excludes valid PC-relative addresses). The
	severity of the resulting diagnostics can be controlled via command
	line option or directive.

	* config/tc-i386.c (set_check): Renamed from set_sse_check.
	Generalize to also handle operand checking option.
	(enum i386_error): New enumerator 'invalid_vector_register_set'.
	(match_template): Handle it.
	(enum check_kind): Give it a tag. Drop sse_ prefixes from
	enumerators.
	(operand_check): New.
	(md_pseudo_table): Add "operand_check".
	(check_VecOperands): Don't special case RIP addressing. Check
	that vSIB operands use distinct vector registers unless no
	checking was requested.

	(md_parse_option): Handle it.
	(OPTION_MAVXSCALAR, OPTION_X32): Adjust.
