Hello,
Masks QI mode size are of extreme importance for AVX-512F,
so I propose to modify my commit [1] and allow kmovb to be
generated on non- AVX512DQ targets.

This also fixes ICE on Spec2k6/453.povray.

Bootstrapped and reg-tested.

If no objections, I'll commit by the EOW.

gcc/
	* config/i386/i386.md (define_mode_iterator SWI1248_AVX512BW): New.
	(define_insn "*k<logic><mode>"): Use new iterator.
