Seems mostly ok.  I don't see the need to construct a scope tree.
Such already exists at DECL_INITIAL (cfun->decl).  All you need is
to (ab)use BLOCK_NUMBER to record the block levels, so that you 
can reemit the notes.  Which should be just fine, since BLOCK_NUMBER
isn't used until final.

I do worry about this, particularly for non-dwarf3 debug targets.
Not sure what to do about it though.
