Add a bit to IdentifierInfo that acts as a simple predicate which
tells us whether Preprocessor::HandleIdentifier needs to be called.
Because this method is only rarely needed, this saves a call and a
bunch of random checks. This drops the time in HandleIdentifier
from 3.52ms to .98ms on cocoa.h on my machine.
