[PATCH] D99661: [SemaObjC] Fix a -Wbridge-cast false-positive

[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak added a comment.

I see a warning when I compile the following (contrived) example:

  typedef const struct __attribute__((objc_bridge(NSError))) __CFString * CFStringRef;
  
  extern "C" {
    typedef const struct __attribute__((objc_bridge(NSString))) __CFString * CFStringRef;
  }
  
  @interface NSString @end
  @interface NSError @end
  
  void CFStringGetLength(CFStringRef theString);
  
  int main() {
    CFStringGetLength((__bridge CFStringRef)(NSString *)0);
  }

Should we try to restore the behavior prior to https://reviews.llvm.org/rG09abecef7bbfda18d34f046954eaa4d491062839 as much as we can? Or that's not important?
