Craig Topper ef85498e05 [Reassociate] Support some reassociation of vector xors ...

Summary:
Currently we don't try to do anything with vector xors.

This patch adds support for removing duplicate pairs from a chain of vector xors as its pretty easy to support. We still dont' try to combine the xors with and/ors, but I might try that in a future patch.
