    rs6000: Convert the vector set variable idx to DImode [PR98914]

    vec_insert defines the element argument type to be signed int by ELFv2
    ABI.  When expanding a vector with a variable rtx, convert the rtx type
    to DImode to support both intrinsic usage and other callers from
    rs6000_expand_vector_init produced by v[k] = val when k is long type.
