-----------
Partially revert my patch of 2008-11-12 that installed a limit on the number
of AND/OR clause branches that predtest.c would attempt to deal with.  As
noted in bug #4721, that change disabled proof attempts for sizes of problems
that people are actually expecting it to work for.  The original complaint
it was trying to solve was O(N^2) behavior for long IN-lists, so let's try
applying the limit to just ScalarArrayOpExprs rather than everything.
Another case of "foolish consistency" I fear.

Back-patch to 8.2, same as the previous patch was.
