This one sucks.
The range of the `test` of `if (a /* comment */) {}` is only `a` and doesn't include the comment nor parenthesis. This means that we have no way to know if the comment is placed before or after the `)` unless you look at the actual source and strip all the whitespace/comments characters to see if it's a `)`...
This happened on the babel source code twice and many times in the fb codebase. I think we need to fix it unfortunately :(
