1) Make the checked assertions a bit more precise. We really want the
canonical forms coming out of reassociate to be exactly what is
expected.
2) Remove other passes, and switch the test to actually directly check
that reassociate makes the important transforms and
canonicalizations.
3) Fold in a related test case now that we're using FileCheck. Make the
same tidying changes to it.
