    middle-end/103038 - avoid ICE with -ftrivial-auto-var-init=pattern

    This avoids ICEing with expanding a VIEW_CONVERT_EXRP of a SSA name
    on the LHS by making sure we can native-interpret OFFSET_TYPE and
    by never building such a LHS but instead view-converting the RHS
    for SSA LHS.

            PR middle-end/103038
            * fold-const.c (native_interpret_expr): Handle OFFSET_TYPE.
            (can_native_interpret_type_p): Likewise.
            * internal-fn.c (expand_DEFERRED_INIT): View-convert the
            RHS if the LHS is an SSA name.

            * g++.dg/pr103038.C: New testcase.
