Make ty::print::Printer take &mut self instead of self

Browse Source 
This simplifies the code by removing all the `self` assignments and
makes the flow of data clearer - always into the printer.
Especially in v0 mangling, which already used  `&mut self` in some
places, it gets a lot more uniform.
