Moved passing tests from pending to files.
Most are pattern matcher bugs fixed by virtpatmat. A few are reifier, package object, or miscellaneous. I threw in an original test for SI-2337, to go with those for SI-1697, SI-3705, SI-4415, and SI-1357, all of which (in the interests of making sure this basket has all the eggs) I am closing.
