* Determine whether this optional chain or nullish coalescing operation has any await statements in
* it. If so, we'll need to transpile to an async operation.
*
* We compute this by walking the length of the operation and returning true if we see an await
* keyword used as a real await (rather than an object key or property access). Nested optional
* chain/nullish operations need to be tracked but don't silence await, but a nested async function
* (or any other nested scope) will make the await not count.
