* Bug replication test
* Simplify test
* Fixes#10896
* Merge path.crawl `ClassDeclaration` and `Declaration` visitors
Merged to avoid subtle assumption that `Declaration` is called before `ClassDeclaration`
* Move registartion of class id in crawl to BlockScoped
* Add some assertions to crawl test
* fix: parameter expression closure should not have access to the declaration inside function body
* fix: renameVisitor should skip when a pattern is a scope
* address review comments
* Don't use args rest/spread to hoist super method calls
* Hoist this in hoisted super method calls
* Make the code more readable

* @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
When traversing a tree parsing for TypeScript syntax and hitting a `TSFunctionType` node, the `typeParameters` and `typeAnnotation` fields are correctly visited but the `parameters` field isn't. As a result visitors by default don't visit `foo` below:
```
var x: (foo) => void; // foo is never visited
```
```
module.exports = function() {
return {
visitor: {
Identifier(path) {
if (path.node.name == "foo") {
// Never hit because it's nested within TSFunctionType.parameters
path.node.name = "bar";
}
}
}
};
}
```
It appears to be a bug in babel-types/src/definitions/typescript.js which omits `parameters` in the visitors list for `fnOrCtr`. Fixed by adding it.
* Add parser createParenthesizedExpressions option …
When set to `true` we create `ParenthesizedExpression` nodes instead of
setting `extra.parenthesized`.
* Also update babel-parser.d.ts
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.
* Add parser createParenthesizedExpressions option …
When set to `true` we create `ParenthesizedExpression` nodes instead of
setting `extra.parenthesized`.
* Also update babel-parser.d.ts
* Migrate try-catch duplicate error
* Remove exception for functions and let in the same scope
* Migrate duplicate bindings tests to traverse
* Add test for subscope and let/const
* Add more test cases
