sse.md (vec_set_lo_<mode><mask_name>, [...]): Add && <mask_avx512dq_condition> condition.

	* config/i386/sse.md (vec_set_lo_<mode><mask_name>,
	vec_set_hi_<mode><mask_name>): Add && <mask_avx512dq_condition>
	condition.  For !TARGET_AVX512DQ, emit 32x4 instruction instead
	of 64x2.

	* gcc.target/i386/avx512dq-vinsert-1.c: New test.
	* gcc.target/i386/avx512vl-vinsert-1.c: New test.
