Fix ExecMakeTableFunctionResult to verify that all rows returned by a SRF
returning "record" actually do have the same rowtype. This is needed because the parser can't realistically enforce that they will all have the same typmod, as seen in a recent example from David Wheeler. Back-patch to 8.0, which is as far back as we have the notion of RECORD subtypes being distinguished by typmod. Wheeler's example depends on 8.4-and-up features, but I suspect there may be ways to provoke similar failures before 8.4.
