Late with code review, but since you have ActOnObjCBoolLiteral(SourceLocation 
OpLoc, tok::TokenKind Kind), why not use that now? I assume that's why it was 
even introduced...to AVOID this cast dance.

(The names are confusing me, too... ActOnObjCBoolLiteral is handling both 
__objc_yes and @__objc_yes (...and @true).)
