codeview: remove hack for handling local labels

Browse Source 
Now when labels are properly concatenated in common code, there is no
reason for the debugging backend to need to be aware of local
symbols.  We don't have to consider ..[^@] special symbols either, as
they are now filtered in labels.c.
