4daf11528c Return inserted/replaced paths (#5710) 
* Return inserted/replaced paths

This gives `Path`’s replacement and insertion methods a consistent
return value: the inserted/replaced paths.

Before, they could return `undefined`, a `node`, or a the current path
inside an array. It was kinda pointless.  But now they always return an
array of paths, which is useful for solving
https://github.com/babel/babel/pull/4935#discussion_r96151368.

* Return inserted nodes and not BlockStatement

Addded test for bug #4363

* Cleanups

- `#replaceWith` will now return the current path if it's the same node
- `#insertAfter` and `#insertBefore` use public Path APIs now
- Makes container insertion faster (single splice call)
- Use public APIs in container insertion
- Replacing a statement with an expression returns the expression's path
- Replacing an expression with multiple statements returns the inserted
  closure's body's paths.

ca117e08cb fix(requeue): Always requeue implicitely created BlockStatements (#6193) 
This reverts the former fix done in #5743 and always requeues
BlockStatements when they get created.

This also fixes a bug in babel-generator which would indent code
even though no comments are present.

4ca686b7be Fix relative execution location introspection (#5741) 
So, I was reading the new Flow type strictness and noticed
https://flow.org/blog/2017/05/07/Strict-Function-Call-Arity/
Specifically, I wondered whether the `sum_all` example would copy the
arguments into an array, then loop over. Sadly, it does.

```js
function sum_all(...rest) {
  let ret = 0;
  for (let i = 0; i < rest.length; i++) { ret += rest[i]; }
  return ret;
}

// output
function sum_all() {
  var ret = 0;
  for (var _len = arguments.length, rest = Array(_len), _key = 0; _key < _len; _key++) {
    rest[_key] = arguments[_key];
  }
  for (var i = 0; i < rest.length; i++) { ret += rest[i]; }
  return ret;
}
```

But then I noticed if I changed `let i = 0` to `let i: number = 0`, it
worked directly on `arguments`. That lead me down a rabbit hole to
`Path#_guessExecutionStatusRelativeTo`. When tracing through, the last
comparison made no sense to me. It was trying to find the index of
`"init"` in a list of `["declarations"]` and `"body"` in `["directives",
"body"]`. Red flags and such.

But it makes sense when you're trying to compare the visitor order of
the common ancestor path. Then we're trying to find `"init"` in a list
of `["init", "test", "update", "body"]`. Oh, and there's `"body"` in
there too! And now we know the `ForStatement`'s `init` is executed
before the `body`.
