Remove invalid private name tests and guard against missing bindings

Inner classes have access to outer private names.

Fixes #2039

According to sec-identifiers-static-semantics-assignmenttargettype,
`AssignmentTargetType` of `arguments` and `eval` in non-strict mode code is

sec-update-expressions-static-semantics-early-errors mandates early errors for
`UpdateExpression` if `AssignmentTargetType` is `invalid` or `strict`.
