Fixes #913

Ref #850

Closes #867
Ref #865

Extend the test generation tool to emit the recently-modified format of
the "negative" meta-data. Update the effected test case files
accordingly.

* Extend tests for class "name" inference

Ensure that when a class defines a static "name" method, that method
definition prevents the "name" inference behavior.

* Re-generate tests

Utilize the test generation tool to increase coverage of destructuring
assignment semantics. Previously, only destructuring assignment in the
AssignmentExpression position was tested. With this change applied, the
same tests will assert expected behavior for destructuring assignment in
`for..of` statements, as well.

A limited number of tests are applied to the `for..in` statement as
well, but due to the iteration protocol observed by that statement, many
destructuring tests are not relevant, and others cannot be automatically
generated from this format.
