No, that's a different thing entirely.  The only way to get rid of it
would be to stop stack-allocating it, and allocate/free it each time
through the loop.

The more I look at it the less inclined I am to merge dwarf2_cu and
dwarf2_per_cu_data; I'd rather find acceptable names for them.  The
dwarf2_per_cu_data is all the information we need to keep for every
compilation unit, including the not-read-in ones.  The dwarf2_cu is all
the information we need to keep around for read-in ones.  I like the
explicit separation.

The only thing weird about the list manipulation is, well, the list
pointer is only needed for read-in ones... so it went in the second
structure.

How do you feel about this?
