Make the RedundancyElimination handle all simplified operators that are listed in the SIMPLIFIED_CHECKED_OP_LIST, and fix a couple of bugs and oversights in the code. This also adds a lot of test coverage for all the cases that we care about in RedundancyElimination (with respect to Check/Checked simplified operators).
