Justin Ridgewell de1431e8c6 Replace arrow expression body with block statement ...

Original PR: https://github.com/babel/babel/pull/2469. Seems this got
lost in the v6 changes.

Without this, the only way to replace the arrow function is to either
manually override its `node.body`, or duplicate the arrow:

```js
// Old
ArrowFunctionExpression: function (node) {
  node.body = t.blockStatement(...);
  // Or
  return t.ArrowFunctionExpression(
    node.params,
    t.blockStatement(...),
    node.async
  );
}

// New
ArrowFunctionExpression: function() {
  this.get("body").replaceWith(t.blockStatement(...));
}
```
