Reverted changes to getShadowOriginPtrUserspace()
Dima noticed that the problem we're trying to solve is essentially inserting two code snippets (one for shadow calculation and one for address check) right before the store to a given address so that the second snippet goes before the first one.
Therefore it's natural to insert the second snippet, and then the first one, i.e. to swap the order of calling materializeStores() and materializeChecks().
