Joyee Cheung 31a951d875 [class] implement access of private methods
This patch implements the access of private methods:

- When building property loads, check whether it requires
  a brand check. If so, build the brand check and load the
  property (the method) from the context instead.
- Throw type errors when there is an attempted write to private
  methods.
