Roslyn Tokenizer Infrastructure (#10676)
This is some of the infrastructure that will be needed to get the Roslyn tokenizer in. We'll have the new tokenizer, and an option to switch back to the legacy tokenizer. To make reviewing easier, I would highly suggest going commit-by-commit, to make sure that the renames show up as actual renames.
