[i386] APX EGPR: fix missing patterns that prohibit egpr

For some pattern m/Bm constraint in alternative 0 and 1 could result in
egpr allocated on memory operand under -mapxf. Should use jm/ja instead.

gcc/ChangeLog:

	* config/i386/sse.md (vec_concatv2di): Replace constraint "m"
	with "jm" for alternative 0 and 1 of operand 2.
	(sse4_1_<code><mode>3<mask_name>): Replace constraint "Bm" with
	"ja" for alternative 0 and 1 of operand2.
