Use RAII to save and restore scalars
This patch replaces many (but not all) uses of
make_cleanup_restore_integer with a simple RAII-based template class.
It also removes the similar restore_execution_direction cleanup in
favor of this new class. Subsequent patches will replace other
similar cleanups with this class.
The class is typically instantiated using make_scoped_restore. This
allows for template argument deduction.
