core: load pages if not loaded
...
Since pages are now tracked with a single centralized structure, it is
possible for a page to have been unloaded a be kept in memory for
metadata purposes like going back in the stack.
Using the example of going to a parent page which was unloaded for
whatever reason: in this case we need to check if it's loaded, if not,
we load it. Locked still means the same thing, loaded just means the
contents of a page are present in memory and if they are present, they
must be in cache.

Removed MemPage from the code in favor of an array to encode the stack

access.
