Further reductions for and/or

[bitner]

This PR adds further reductions in the case of and/or operations.

• If there are any nested arguments that are of the same operator (and or or), move those arguments up into the higher and/or.
• Remove duplicate expressions from the and/or arguments
• Short circuit and if there are ANY false records for AND, return false.
• Short circuit and if there are ANY true records for OR, return true.
• If the arguments are reduced to a single expression, return just that expression.

Sorry, I'll have time for a more throughough review next week, but just a quick nit check
