	PR target/70927
	* config/i386/sse.md (<sse>_andnot<mode>3<mask_name>),
	*<code><mode>3<mask_name>): For !TARGET_AVX512DQ and EVEX encoding,
	use vp*[dq] instead of v*p[sd] instructions and adjust mode attribute
	accordingly.

	* gcc.target/i386/avx512vl-logic-1.c: New test.
	* gcc.target/i386/avx512vl-logic-2.c: New test.
