You posted your question three hours ago.  Generally it takes at least
a day to get an answer out of anyone.

I find either (1) or (3) infinitely preferable to (2), and would
suggest you consider a (3a) in which the ObjC/ObjC++ front ends
enlarge the C/C++ lang_type structures (in much the same way that all
these front ends currently build on struct c_common_identifier to
create their struct lang_identifier).  This is preferable to (3) if
the additional data is small (up to, say, four pointers), or if it
needs allocating for practically every RECORD_TYPE.  If it is both
large and rarely needed, your original (3) is better.

You should determine the answer to the question "is it rarely needed?"
by measurement of real code.
