    rs6000: MMA built-ins reject typedefs of MMA types

    We do not allow conversions between the MMA types and other types.
    However, we are being too strict in not matching MMA types with
    typdefs of those types.  Use TYPE_CANONICAL to see through the
    types to their canonical types before comparing them.
