Now that some implicit bridging conversions were removed, we can remove some of
the complex String comparison overloads. We could not remove all of them yet, as
String to NSString implicit bridging still exists. To work around this,
unavailable annotations were used. This ensures the user always gets the String
comparison function they intended.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

This decreases total testing time by over a minute on my old Mac Pro.
It probably has much less effect on systems with fewer cores, but shouldn't
be any worse there.
