Implements an efficient mapping from strings to IdentifierInfo nodes.
This has no other purpose, but this is an extremely performance-critical piece of the code, as each occurrence of every identifier goes through here when lexed.

Gets an IdentifierInfo for the given name without consulting external sources.
This is a version of get() meant for external sources that want to introduce or modify an identifier. If they called get(), they would likely end up in a recursion.
