This also allows us to enable the assert in IrType::IrType. Unfortunately, this is mostly a "peace of mind" commit, there doesn't seem to have been a bug actually caused by the transitory duplicate IrTypePointer/IrTypeStruct instances. The remaining xyz2llvm static methods are not exactly pretty, they should probably just be folded into get.
