Many AVX2 tests have things like:

[hjl@gnu-6 i386]$ head -10 avx2-vmovmskb-2.c
/* { dg-do compile } */
/* { dg-options "-mavx2 -O2" } */
/* { dg-final { scan-assembler "vmovmskb" } } */

It scans vmovmskb, which is also the part of filename:

[hjl@gnu-6 gcc]$ head avx2-vmovmskb-2.s
    .file    "avx2-vmovmskb-2.c"
    .text
    .p2align 4,,15
    .type    do_test, @function

Even if there is no vmovmskb instruction at all, the scan
still passes.  We should add -dp:

/* { dg-options "-mavx2 -O2 -dp" } */

and scan the proper pattern name.

Also avx2-vmovmskb-2.c should be avx2-vpmovmskb-2.c.
