Log:
	PR target/80206
	* config/i386/sse.md
	(<extract_type>_vextract<shuffletype><extract_suf>_mask): Use
	register as dest whenever it is a MEM not rtx_equal_p to the
	corresponding dup operand, and when forcing into reg move the
	reg into the memory afterwards.
	(<extract_type_2>_vextract<shuffletype><extract_suf_2>_mask):
	Likewise.  Use <ssehalfvecmode> instead of <ssequartermode>
	for the force_reg mode.
	(avx512vl_vextractf128<mode>): Use register as dest either
	always when a MEM, or when it is a MEM not rtx_equal_p to the
	corresponding dup operand, or even not when it is a CONST_VECTOR
	depending on the mode and lo vs. hi.
	(avx512dq_vextract<shuffletype>64x2_1_maskm): Remove extraneous
	parens.
	(avx512f_vextract<shuffletype>32x4_1_maskm): Likewise.
	(<mask_codefor>avx512dq_vextract<shuffletype>64x2_1<mask_name>):
	Likewise.  Require that operands[2] is even.
	(<mask_codefor>avx512f_vextract<shuffletype>32x4_1<mask_name>):
	Remove extraneous parens.  Require that operands[2] is a multiple
	of 4.
	(vec_extract_lo_<mode><mask_name>): Don't bother testing if
	operands[0] is a MEM if <mask_applied>, the predicates/constraints
	disallow memory then.

	* gcc.target/i386/pr80206.c: New test.
