    analyzer: fix ICE on function pointer casts [PR 93775]

    PR analyzer/93775 reports an ICE in cgraph_node::get when -fanalyzer is
    used on code that calls a function pointer that was generated via a cast
    from a non-function.

    This patch fixes it by bulletproofing region_model::get_fndecl_for_call
    for the case where the code_region's get_tree_for_child_region returns
    NULL.

    gcc/analyzer/ChangeLog:
        PR analyzer/93775
        * region-model.cc (region_model::get_fndecl_for_call): Handle the
        case where the code_region's get_tree_for_child_region returns
        NULL.
