    testsuite: i386: Fix gcc.target/i386/avx512f-pr96891-3.c on Solaris [PR102834]
    
    gcc.target/i386/avx512f-pr96891-3.c currently FAILs on 32-bit Solaris/x86:
    
    FAIL: gcc.target/i386/avx512f-pr96891-3.c scan-assembler-times
    (?n)vpcmp[bwdq][ \\\\t]*\\\\\$7 4
    
    There are only 3 instances of the expected pattern because Solaris/x86
    defaults to -mno-stv.  Fixed by compiling with -mstv and
    -mno-stackrealign.  Tested on i386-pc-solaris2.11 and
    x86_64-pc-linux-gnu.
