    ipa/119067 - bogus TYPE_PRECISION check on VECTOR_TYPE

    odr_types_equivalent_p can end up using TYPE_PRECISION on vector
    types which is a no-go.  The following instead uses TYPE_VECTOR_SUBPARTS
    for vector types so we also end up comparing the number of vector elements.

            PR ipa/119067
            * ipa-devirt.cc (odr_types_equivalent_p): Check
            TYPE_VECTOR_SUBPARTS for vectors.

            * g++.dg/lto/pr119067_0.C: New testcase.
            * g++.dg/lto/pr119067_1.C: Likewise.
