    middle-end/110182 - TYPE_PRECISION on VECTOR_TYPE causes wrong-code

    When folding two conversions in a row we use TYPE_PRECISION but
    that's invalid for VECTOR_TYPE.  The following fixes this by
    using element_precision instead.

            PR middle-end/110182
            * match.pd (two conversions in a row): Use element_precision
            to DTRT for VECTOR_TYPE.
