If you want to make the parameter and argument label the same in
places where you don't get the argument label for free (i.e., the
first parameter of a function or a parameter of a subscript),
double-up the identifier:
func translate(dx dx: Int, dy: Int) { }
Make this a warning with Fix-Its to ease migration. Part of

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.

Also warn when the subclass returns 'T!' where the superclass returns 'T?'.
In both cases, allow silencing by wrapping the 'T!' in parentheses.
This is intended to provide migration help as Objective-C classes get
annotated for nullability. Because of that, the check is only run on @objc
classes, though it's not limited to classes that actually come from Objective-C
because of (a) deep subclass chains that may all need updating, and (b) ease
of testing.
