In several places we use helper methods to more easily instantiate classes when there will be a lot of instances.
Unfortunately, that means the $$createdAt for each of them points to the same place - the helper method - and doesn't give any information on the call stack which got to the helper method, which is what we really want to know when debugging.
This PR adds a new compiler flag, verboseCreatedAt, which is off by default. When enabled, this adds a stack field to the $$createdAt object. When debugging, it can be used to find exactly where we deferred control to some automation rather than simply the point where the new expression was written (as in the existing fields).
Downside: the line and column numbers are generated by the native Error class, which in the runtimes I've tested does not read source maps, so line and column numbers often won't match source code.
enabling this flag won't remove the existing $$createdAt fields, they still are/are not present based solely on addCreatedAt.
