I take it back --- the short-circuit test already exists, but it's at
the call sites rather than in tuptoaster.c.
However, it looks like we can tighten the tests a bit. For instance
heap_delete invokes the toaster if HeapTupleHasExtended, whereas it
seems to me it'd be sufficient to check HasExternal --- we don't care
about deleting compressed-in-line stuff, do we?
