When printing an ObjC member into a header with an `Int` parameter or result, PrintAsClang would look up any imported Objective-C member it overrode to see if ClangImporter imported `NSUInteger` as `Int`, and if so, would print `NSUInteger` instead of `NSInteger`. However, it did not do the same for protocol requirements the member witnessed. Correct this oversight.
Fixes rdar://124300674.
We were printing getter/setter names when the property came from
Objective-C initially, which is incorrect: we should print them when
the names differ from what Objective-C would compute by default. This
finishes rdar://problem/19408726, which was mostly in place a while
ago.
Swift SVN r28783
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.)
