Sean Callanan 5c35f7cfd1 Cleaned up the StringLexer a little bit. It turns
out we only want to roll back text that was in the
buffer to begin with, so it's not necessary to
provide a pushback stack.

I'm going to use this slightly cleaner API to perform
lookahead for the Objective-C runtime type parser.
