  [Attributor] Make heap2stack record alloca placement

We recently learned to place the alloca during the heap2stack
transformation in the entry block but we did not account for other
concurrent modifications. We need to record our decision rather than
checking (then outdated) passes during the manifest stage. This will
also allow us to use a custom (=optimistic) "loop info" in the future.
