   Why not add another member to `enum return_value_convention' so that 
   return_value() can directly differentate between these two cases?

I thought about that.  Returning an address from gdbarch_return_value
is a bit weird.  Hmm, it just occurs to me that we make a copy of the
value and have gdbarch_return_value return that.  Hmm, back to the
drawing board.  Expect a new patch soon.
