nit: this seems redundant since by definition if you're calling a method which
takes an enum value, that header must have included the enum

Fair enough. Removed.

 
 // The implementation of NSExceptions break various assumptions in the
 // Chrome code.  This category defines a replacement for
 // -initWithName:reason:userInfo: for purposes of forcing a break in
 // the debugger when an exception is raised.  -raise sounds more
 // obvious to intercept, but it doesn't catch the original throw
 // because the objc runtime doesn't use it.
