This moves the code to allocate the far jump table from
{SetRuntimeStubs} to {AddCodeSpace} to allocate one such table per code
space.
Also, the {runtime_stub_table_} and {runtime_stub_entries_} fields do
not make sense any more now and are replaced by calls to
{GetNearRuntimeStubEntry} and {GetRuntimeStubId}.
