Reviewers: Michael Starzinger, Yang,
Description:
[runtime] Add %ToString and %_ToString and remove the TO_STRING builtin.
This adds a new ToString runtime function and a fast-path ToStringStub
(which is just a simple dispatcher for existing functionality), and also
implements %_ToName using the ToStringStub.
