    [i386] Fix testcases for emulated scatter
    
    The following adjusts testcases where the pr88531 fail with -m32
    because we do not consider MMX size vectorization there and the
    pr89618 runs into load/store cost differences with -m32.
    
            * gcc.target/i386/pr88531-2a.c: Skip scanning for ia32.
            * gcc.target/i386/pr88531-2b.c: Likewise.
            * gcc.target/i386/pr88531-2c.c: Likewise.
            * gcc.target/i386/pr89618-2.c: Likewise.  Disable AVX512.
