Original commit message:
[builtins] Make Promise resolvers not keep resolved Promises alive
Currently a Promise's resolve/reject functions unconditionally hold the
Promise, plus a separate bit to track whether the Promise has been
resolved. Instead, hold a single field with Promise|Undefined.
This allows GC'ing a resolved Promise even if its resolvers are still
alive.
