Treat aggregate direct arguments as per-agg data not per-trans data.
There is no reason to insist that direct arguments must match before
we can merge transition states of two aggregate calls. They're only
used during the finalfn call, so we can treat them as like the finalfn
itself. This
Fix incorrect handling of CTEs and ENRs as DML target relations.
setTargetTable threw an error if the proposed target RangeVar's relname
matched any visible CTE or ENR. This breaks backwards compatibility in
the CTE case, since pre-v10 we never looked for a CTE here at all, so that
CTE names did
Repair breakage of aggregate FILTER option.
An aggregate's input expression(s) are not supposed to be evaluated
at all for a row where its FILTER test fails ... but commit 8ed3f11bb
overlooked that requirement. Reshuffle so that aggregates having a
filter clause evaluate their arguments

Allow the built-in ordered-set aggregates to share transition state.
The built-in OSAs all share the same transition function, so they can
share transition state as long as the final functions cooperate to not
do the sort step more than once. To avoid running the tuplesort object
in randomAccess
Exclude flex-generated code from coverage testing
Flex generates a lot of functions that are not actually used. In order
to avoid coverage figures being ruined by that, mark up the part of the
.l files where the generated code appears by lcov exclusion markers.
That way, lcov will typically only
