5f764d8527 Move type base classes into type/ folder.
This CL moves sem/type and copies sem/node into the type/ folder. The
type subclasses are moved over to using type::Type while remaining in
the sem:: namespace. They will be moved over in followup CLs.

6251598ad2 tint: Add DemoteToHelper transform
This transform implements demote-to-helper semantics for discard
