Joyee Cheung 00c7e2a2c5 Reland "[class] implement private method declarations" 
Added null check when printing the brand with --print-ast.

Bug: chromium:961507, chromium:961508

Original change's description:
> [class] implement private method declarations
>
> This patch implements the declarations of private methods, the access
> of private methods would be left to a future patch.
> When a private methods declaration is encountered, we now:
>
> - Create a brand symbol during class evaluation and store it in the
>   context.
> - Create the closures for the private methods
> - Load the brand from the context and store it in the instance in the
>   constructor.
>
> Design: https://docs.google.com/document/d/1T-Ql6HOIH2U_8YjWkwK2rTfywwb7b3Qe8d3jkz72KwA/edit#
>
