1) Try to make new nodes from conjunctions applied to the top RSE of a UNION.
...
Deliver the new nodes (created per rse inside the union) to the optimizing phase of every rse.
2) Little refactoring of above function and the one for aggregate

Distribute HAVING clause conjunctions to the WHERE clause when possible.
...
This will improve VIEWs that contain a aggregate query and comparisons are done on fields from that VIEW that are also part of the GROUP BY clause.

MSVC6 doesn't keep variables in a for() only in that scope. This standard construction is rejected:
...
for (int i = ...);
for (int i = ...);
Put the variable again before the loops to be able to compile.

Small optimization of multiple OR booleans (or a constant IN predicate).
...
The idea is to use a single sparse bitmap for an index matching and hence avoid OR'ing bitmaps for every argument value.
