includes a number of QoI things to help people write the correct code. I will commit the testcase for it as the next patch. The bulk of this patch is moving the stdlib, testsuite and validation testsuite to the new syntax. I moved a few uses of "as" patterns back to as? expressions in the stdlib as well. Swift SVN r27959
