    lto/94822 - fix ICE in component_ref_size

    This ICE appears because gcc will stream it to the function_body section
    when processing the variable with the initial value of the constructor
    type, and the error_mark_node to the decls section.
    When recompiling, the value obtained with DECL_INITIAL will be error_ma=
rk.
