    Make xxsplti*, xpermx, xxeval be vecperm type.
    
    I noticed that the built-functions for xxspltiw, xxspltidp, xxsplti32dx,
    xxpermx, and xxeval all used the 'vecsimple' type.  These instructions are
    permute instructions (3 cycle latency) and should use 'vecperm' instead.
    
    While I was at it, I changed the UNSPEC name for xxspltidp to be
    UNSPEC_XXSPLTIDP instead of UNSPEC_XXSPLTID.

            * config/rs6000/vsx.md (UNSPEC_XXSPLTIDP): Rename from
            UNSPEC_XXSPLTID.
            (xxspltiw_v4si): Use vecperm type attribute.
            (xxspltiw_v4si_inst): Use vecperm type attribute.
            (xxspltiw_v4sf_inst): Likewise.
            (xxspltidp_v2df): Use vecperm type attribute.  Use
            UNSPEC_XXSPLTIDP instead of UNSPEC_XXSPLTID.
            (xxspltidp_v2df_inst): Likewise.
            (xxsplti32dx_v4si): Use vecperm type attribute.
            (xxsplti32dx_v4si_inst): Likewise.
            (xxsplti32dx_v4sf_inst): Likewise.
            (xxblend_<mode>): Likewise.
            (xxpermx): Likewise.
            (xxpermx_inst): Likewise.
            (xxeval): Likewise.
