Log Message: ----------- Don't try to constant-fold functions returning RECORD. We were never able to do this before, but I had tried to make an exception for functions with OUT parameters. Michael Fuhr found one problem with it already, and I found another, which was it didn't work for strict functions with a NULL input. While both of these could be worked around, the probability that there are more gotchas seems high; I think prudence dictates just reverting to the former behavior for now. Accordingly, remove the kluge added to get_expr_result_type() for Michael's case.
