extract_jsp_bool_expr applied De Morgan's laws incorrectly when considering an AND operator underneath a NOT. If one AND input was implementable as a GIN indexqual while the other was not, we derived an incomplete indexqual, leading to some rows not being returned that should be. extract_jsp_bool_expr also failed to check for methods being applied to literals, so that for example '$.x == "42".double()' was treated as '$.x == "42"' not '$.x == 42'. The indexqual thus selected the wrong rows, all of which would fail qual recheck, leading to no rows being returned. While we're here, improve the comments a trifle.
