8433: Intern lots of things r=jonas-schievink a=flodiebold

This uses the new interning infrastructure for most type-related things, where it had a positive effect on memory usage and performance. In total, this gives a slight performance improvement and a quite good memory reduction (1119MB->885MB on RA, 1774MB->1188MB on Diesel).
