72161a64b2 @babel/traverse: Fix NodePath.getData (#9415)
* @babel/traverse: Fix NodePath.getData

Currently, if the obtained value is `false`, it will be replaced by the given default value, which is invalid. This makes sure that we only set the default value when the value is `undefined`, instead of falsy.

* Add test and fix object protoype

* Allow false as default value

Use for..of Object.keys instead of for..in (#9518)
In https://github.com/babel/babel/issues/9511 (and #9495 is another symptom), @PavelKastornyy reported a node crash becaue the JavaScript heap run out of memory. The problem was that their code was adding enumerable properties to `Object.prototype`: it is something that shouldn't be done, but Babel shouldn't make node crash if someone adds them.
I reduced down the problem to `for...in` loops in `@babel/traverse` that grew the memory consumption exponentially because of that unexpected properties.

* [decorators] Correctly insert `_initialize(this)` after `super()`.

This commit fixes to problem:
1) After `super();` statements, `_initialize(this)` was inserted without
   a trailing semicolon.
2) `(0, super())` causes an infinite recursion.
