r297702 - [CodeGen][ObjC] Fix a bug where the type of an ivar wasn't encoded

[Akira Hatanaka via cfe-commits]

It crashes when there is an anonymous ivar of a bitfield type.

@interface FormatScanner {
  int : 1;
}
@end

@implementation FormatScanner
@end

I'm not sure if the code above is valid or not, but out of curiosity, why would you want an anonymous bitfield variable?
