    vect: Add bool pattern handling for COND_OPs.

    In order to handle masks properly for conditional operations this patch
    teaches vect_recog_mask_conversion_pattern to also handle conditional
    operations.  Now we convert e.g.

     _mask =3D *_6;
     _ifc123 =3D COND_OP (_mask, ...);

    into
     _mask =3D *_6;
     patt200 =3D (<signed-boolean:1>) _mask;
     patt201 =3D COND_OP (patt200, ...);

    This way the mask will be properly recognized as boolean mask and the
    correct vector mask will be generated.

            * tree-vect-patterns.cc (vect_recog_mask_conversion_pattern):
            Convert masks for conditional operations as well.
