And remove a whole load of const_cast hackery. Semantic nodes may contain internally mutable fields (although only ever modified during resolving), so these are always passed by `const` pointer. While all AST nodes are internally immutable, we have decided that pointers to AST nodes should also be marked `const`, for consistency. There's still a collection of const_cast calls in the Resolver. These will be fixed up in a later change.
