[dmd-internals] test failures

[Brad Roberts]

core.exception.AssertError at std/datetime.d(842): _assertPred!("opCmp", "<") failed: [-1999-Jan-01 23:59:59] ==
[-1999-Jan-01 23:59:59].

Nothing changed near the phobos portion of this code, and it's been failing since this set of changes on all but
windows.  The only reason windows isn't failing, I suspect, is that a bunch of the datetime tests are versioned out.
