    gcc.target/i386/avx512vl-stv-rotatedi-1.c FAILs on 32-bit Solaris/x86
    since its introduction in

        i386: Add AVX512 support for STV of SI/DImode rotation by constant.

    While the test depends on -mstv, 32-bit Solaris/x86 defaults to
    -mstackrealign which is incompatible.
    
    The patch thus specifies -mstv -mno-stackrealign explicitly.
    
    Tested on i386-pc-solaris2.11 and i686-pc-linux-gnu.

            * gcc.target/i386/avx512vl-stv-rotatedi-1.c: Add -mstv
            -mno-stackrealign to dg-options.
