Markus Török 6597a472b3 Add "use strict" directive (#7411)
* #7349
- Add "use strict" directive to transformed class bodies

* Update tests (#7349)

* Add test for program with use strict directive (#7349)

* Update tests (#7349)

* Update source mapping (#7349)

* Add test for parent blockStatement with use strict directive (#7349)

* Update tests (#7349)

* Update tests (#7349)

* Update tests (#7349)

* Add test for constructor-only class (#7349)

* Constructor only classes are strict, too

But constructor only that use non-simple parameters must use a strict function wrapper.

* Fix test

* Wrapper not needed if class is already strict

* Revert change to lerna.json
