x86: further PR target/100711-like splitting

With respective two-operand bitwise operations now expressable by a
single VPTERNLOG, add splitters to also deal with ior and xor
counterparts of the original and-only case. Note that the splitters need
to be separate, as the placement of "not" differs in the final insns
(*iornot<mode>3, *xnor<mode>3) which are intended to pick up one half of
the result.

gcc/

	PR target/100711
	* config/i386/sse.md: New splitters to simplify
	not;vec_duplicate;{ior,xor} as vec_duplicate;{iornot,xnor}.

gcc/testsuite/

	PR target/100711
	* gcc.target/i386/pr100711-4.c: New test.
	* gcc.target/i386/pr100711-5.c: New test.
