Log:
	PR target/82460
	* config/i386/sse.md (UNSPEC_VPERMI2, UNSPEC_VPERMI2_MASK): Remove.
	(VPERMI2, VPERMI2I): New mode iterators.
	(<avx512>_vpermi2var<mode>3_maskz): Remove 3 define_expand patterns.
	(<avx512>_vpermi2var<mode>3<sd_maskz_name>): Remove 3 define_insn
	patterns.
	(<avx512>_vpermi2var<mode>3_mask): New define_expand using VPERMI2
	mode iterator.  Remove 3 old define_insn patterns.
	(*<avx512>_vpermi2var<mode>3_mask): 2 new define_insn patterns.
	(<avx512>_vpermt2var<mode>3_maskz): Adjust 1 define_expand to use
	VPERMI2 mode iterator, remove the other two expanders.
	(<avx512>_vpermt2var<mode>3<sd_maskz_name>): Adjust 1 define_insn
	to use VPERMI2 mode iterator, add another alternative for vpermi2*
	instructions, remove the other two patterns.
	(<avx512>_vpermt2var<mode>3_mask): Adjust 1 define_insn to use VPERMI2
	mode iterator, remove the other two patterns.
	* config/i386/i386.c (ix86_expand_vec_perm_vpermi2): Renamed to ...
	(ix86_expand_vec_perm_vpermt2): ... this.  Swap mask and op0
	arguments, use gen_*vpermt2* expanders instead of gen_*vpermi2*
	and adjust argument order accordingly.
	(ix86_expand_vec_perm): Adjust caller.
	(expand_vec_perm_1): Likewise.
	(expand_vec_perm_vpermi2_vpshub2): Rename to ...
	(expand_vec_perm_vpermt2_vpshub2): ... this.
	(ix86_expand_vec_perm_const_1): Adjust caller.
	(ix86_vectorize_vec_perm_const_ok): Adjust comments.

	* gcc.target/i386/pr82460-1.c: New test.
	* gcc.target/i386/pr82460-2.c: New test.
	* gcc.target/i386/avx512f-vpermt2pd-1.c: Adjust scan-assembler*
	regexps to allow vpermt2* to vpermi2* replacement or vice versa
	where possible.
	* gcc.target/i386/avx512vl-vpermt2pd-1.c: Likewise.
	* gcc.target/i386/avx512f-vpermt2d-1.c: Likewise.
	* gcc.target/i386/vect-pack-trunc-2.c: Likewise.
	* gcc.target/i386/avx512vl-vpermt2ps-1.c: Likewise.
	* gcc.target/i386/avx512vl-vpermt2q-1.c: Likewise.
	* gcc.target/i386/avx512f-vpermt2ps-1.c: Likewise.
	* gcc.target/i386/avx512vl-vpermt2d-1.c: Likewise.
	* gcc.target/i386/avx512bw-vpermt2w-1.c: Likewise.
	* gcc.target/i386/avx512vbmi-vpermt2b-1.c: Likewise.
	* gcc.target/i386/avx512f-vpermt2q-1.c: Likewise.
