This is required to correctly use the mock SDK when the SDK overlay is
built and tested separately. (Otherwise, the mock SDK might not get
used, because the overlay SDK options would expand from the
%-substitution, appear first on the command line, and shadow the mock
SDK in the search path).
Swift SVN r25185
If a property, method, or subscript overrides an imported property, method,
or subscript that was originally declared using NSUInteger as a property,
parameter, or return type, print the subclass's member using "NSUInteger"
in the generated header to prevent override warnings.
This doesn't handle all cases--in particular, it doesn't handle the
NSUInteger being nested inside a larger type--but it does get the easy
ones correct. I think the easiest way to be more correct would be to mark
NSUInteger-as-Int somehow using a distinct type. (Hidden attribute?
Another typealias? Not sure.)
