+  PP.Lex(Tok);
+  II = Tok.getIdentifierInfo();
----------------
I'm having trouble figuring out why this isn't a breaking change.  `PP.Lex(Tok)` moves the current 'token' to be the next one (that is, it has side effects!), so now this ends up looking in a different place for the intrin name? 

This will result in `IntrinsicClass` becoming the value of the token 2 after the fact, which doesn't seem right to me.  I suspect the correct answer here is to just move IntrinsicClass ~4050.
