codeview: Don't treat labels starting with .. as local labels

For local labels, starting with '.', the label name is concatenated with
the previous non-local label to produce a label that can be accessed from
elsewhere. This is the name we want to generate debug info for.

Labels starting with ".." are special and shouldn't be concatenated.

Fix Bugzilla #3392342
