I think that following ChangeLog text better describes the change:ž

        PR target/43175
        * config/i386/i386.c (expand_vec_perm_blend): Use correct
        operands in V8HImode subregs.  Fix operand order in VEC_MERGE rtx.

Also, please post patch to gcc-patches@ ML for others to see/comment.
