simplify the new filter condition
233d9dd is described below

[CALCITE-2582] FilterProjectTransposeRule does not always simplify the new
filter condition
1. Simplify newCondition in a similar manner to RelBuilder#filter method.
2. Update tests in misc.iq, sub-query.iq, GeodeZipsTest,
GeodeAllDataTypesTest to reflect the applied simplifications.
