Liu, Hongtao May 26, 2023, 1:48 a.m. UTC 
  r12-5595-gc39d77f252e895306ef88c1efb3eff04e4232554 adds 2 splitter to
transform notl + pbroadcast + pand to pbroadcast + pandn for
VI124_AVX2 which leaves out all DI-element-size ones as
well as all 512-bit ones.
This patch extend the splitter to VI_AVX2 which will handle DImode for
AVX2, and V64QImode,V32HImode,V16SImode,V8DImode for AVX512.

Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ready to push to trunk.

gcc/ChangeLog:

	PR target/100711
	* config/i386/sse.md (*andnot<mode>3): Extend below splitter
	to VI_AVX2 to cover more modes.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr100711-2.c: Add v4di/v2di testcases.
	* gcc.target/i386/pr100711-3.c: New test.
