When binding a name, add it to name lookup. On NameReference nodes, use name lookup. - Switches from "identifiers" to the more generic "strings". Not strictly necessary here, but it's the overall direction I think we've agreed upon and wanted to do it while building more support out. - Starts doing deduplication of strings. - On BindName, registers names with name lookup. - Does name lookup based on the deduplicated string. - Per discussion with zygoloid, design is intended to be constant-time lookup regardless of the number of parent scopes. - Adds scopes so that we can track names which will be deregistered from lookup.
