This seems like a reasonable workaround, especially since we already
have some special handling of attr->form == DW_FORM_block1 for range
types.  So I guess we never have block2/block4 or even block attributes
for the upper bound in practice?

Just one request:

Can you add a quick comment, with a FIXME to show that this is temporary?
There's already some useful comments just slightly earlier in the code,
perhaps we just ought to refer to that, somehow.

Pre-approved with the addition of the comment.
