The __kindof type qualifier can be applied to Objective-C object
(pointer) types to indicate id-like behavior, which includes implicit
"downcasting" of __kindof types to subclasses and id-like message-send
behavior. __kindof types provide better type bounds for substitutions
into unspecified generic types, which preserves more type information.

to provide proper overloading, and also prevents mangling conflicts with

- This is designed to make it obvious that %clang_cc1 is a "test variable"

a default target).
