[PATCH] D82895: [NFC][LoopInfo] Document empty()

[Stefanos Baziotis via Phabricator via llvm-commits]

baziotis added a comment.

I created the review instead of just committing to discuss that it may be a good idea to even rename this e.g. to "isInnermost()".
With "empty()", it's not clear if the implementation is:
`return getSubLoops().empty()` or `return !getNumBlocks()` (or something else)
