    PR target/50911
    * config/i386/i386.c (expand_vec_perm_interleave2): If d->vmode is
    V4SImode, !TARGET_SSE2 and punpck[lh]* is needed, change dremap.vmode
    to V4SFmode.

    * gcc.dg/torture/vshuf-16.inc: Add interleave low and high
    permutations.
    * gcc.dg/torture/vshuf-32.inc: Likewise.
    * gcc.dg/torture/vshuf-4.inc: Likewise.
    * gcc.dg/torture/vshuf-8.inc: Likewise.
