Make TB tree traversal bottom-up
In preparation for #3837, the tree traversal needs to be made bottom-up, because the current top-down tree traversal, coupled with that PR's changes to the garbage collector, can introduce non-deterministic error messages if the GC removes a parent tag of the accessed tag that would have triggered the error first. This is a breaking change for the diagnostics emitted by TB. The implemented semantics stay the same.
