[PATCH] D31839: make -Winteger-overflow find overflows in function arguments

Is it possible to fix ObjCMessageExpr too while you are in here?

I think clang should issue a warning when compiling the following code:

  @protocol NSObject
  @end
  
  @interface NSObject<NSObject>
  @end
  
  @interface C1 : NSObject
  - (void)foo:(int)i;
  @end
  @implementation C1
  - (void)foo:(int)i {
  }
  @end
  
  void test1(C1 *c) {
    [c foo:(4068 * 1024 * 1024)];
  }
