Class private properties (#7842)
* Update member-expression-to-functions

1. Babel using British spellings, so `memoise`
2. Provide a helper `AssignmentMemoiser` class, which will assign the memo'd value with the `n`th access.

* Private properties!

* Fixes

* Tests

* Update helper name

* Fix privates that reference other privates

* Don't extend a builtin

* Rebase
