    Use error_mark_node after error in convert

    While working on PR c/111903, I Noticed that
    convert will convert integer_zero_node to that
    type after an error instead of returning error_mark_node.
    From what I can tell this was the old way of not having
    error recovery since other places in this file does return
    error_mark_node and the places I am replacing date from
    when the file was imported into the repro (either via a gcc2 merge
    or earlier).

    I also had to update the objc front-end to allow for the error_mark_node
    change, I suspect you could hit the ICE without this change though.

    Bootstrapped and tested on x86_64-linux-gnu with no regressions.

    gcc/ChangeLog:

            * convert.cc (convert_to_pointer_1): Return error_mark_node
            after an error.
            (convert_to_real_1): Likewise.
            (convert_to_integer_1): Likewise.
            (convert_to_complex_1): Likewise.

    gcc/objc/ChangeLog:

            * objc-gnu-runtime-abi-01.cc (build_objc_method_call): Allow
            for error_operand after call to build_c_cast.
            * objc-next-runtime-abi-01.cc (build_objc_method_call): Likewis=
e.
            * objc-next-runtime-abi-02.cc (build_v2_build_objc_method_call):
Likewise.=
