6a8de4c9dc Avoid enumerating entire overlay store dir upfront.
As an optimisation for LocalStore, we read all the store directory entries into
a set. Checking for membership of this set is much faster than a stat syscall.
However for LocalOverlayStore, the lower store directory is expected to contain
a vast number of entries and reading them all can take a very long time.

So instead of enumerating them all upfront, we call pathExists as needed. This
means making stat syscalls for each store path, but the upper layer is expected
to be relatively small compared to the lower store so that should be okay.
