    function: Set dummy DECL_ASSEMBLER_NAME in push_dummy_function [PR10058=
0]

    Last year I've added cgraph_node::get_create calls for the dummy
    functions used for -fdump-passes, so that it interacts well with pass
    disabling/enabling which is cgraph uid based.
    Unfortunately, as the following testcase shows, when assembler hash
    is present, that wants to compute DECL_ASSEMBLER_NAME and the C++ FE
    is unprepared to handle it on the dummy functions which don't have
    DECL_NAME etc.
    The following patch fixes it by setting up a dummy DECL_ASSEMBLER_NAME
    on these, so that the FEs don't need to compute it.
