[PATCH] D103434: [analyzer] Allow visitors to run callbacks on completion

[Deep Majumder via Phabricator via cfe-commits]

RedDocMD added a comment.

**Note: This patch is only partially done.**

The following things are still left:

- `trackExpressionValue` must receive a callback
- The callback must be passed to a visitor (`ReturnVisitor` for now)
- Tests to verify that `ReturnVisitor` actually does what we intend it to do (call the callback at the right place).
