The importer had several bugs with respect to labels and gotos: - it didn't create a new ONAME node for label names (label dcl, goto, continue, and break) - it overwrote the symbol for gotos with the dclstack - it didn't set the dclstack for labels In the process changed export format slightly to always assume a label name for labels and gotos, and never assume a label for fallthroughs. For fallthroughs and switch cases, now also set Xoffset like in the parser. (Not setting it, i.e., using 0 was ok since this is only used for verifying correct use of fallthroughs, which was checked already. But it's an extra level of verification of the import.) Fixes #15838.
