ASTScopes must be searched in source order, and when creating them, must be created in source-order. But what is the ordering for a SourceRange? It must be consistent. This PR factors these uses of ordering, so that there is one place, which chooses the ordering of the end locations. It may also fix the problem for Windows, that isNotAfter was not a total order.
