PR target/66369
* config/i386/sse.md (<sse2_avx2>_pmovmsk): Merge from avx2_pmovmskb
and sse2_pmovmskb using VI1_AVX2 mode iterator.
(*<sse>_movmsk<ssemodesuffix><avxsizesuffix>_zext): New insn pattern.
(*<sse2_avx2>_pmovmskb_zext): Ditto.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Committed to mainline SVN.
Uros.
