sql: FILTER applied after evaluating aggregate function expression

[andy-kimball]

Repro:

root@:26257/defaultdb> SELECT SUM(1/x) FILTER (WHERE x > 0) FROM (VALUES (0), (1)) t(x);
ERROR: division by zero

EXPECTED: No error, like PG:

template1=# SELECT SUM(1/x) FILTER (WHERE x > 0) FROM (VALUES (0), (1)) t(x);
 sum
-----
   1

Jira issue: CRDB-5125

Seems hard for us to fix, given the way that we compile aggregate and FILTER expressions. But I filed it so that we're aware of this small behavior difference, and in case we come up with some reasonable way to match semantics.
