Constify Type* constructor args for ast/sem classes
To avoid breaking things, functions that return the type cast away
the constness for now. This, however, makes it easier to use typ::Type
with these classes, as typ::Type stores pointers to const types. This
also brings us one step closer to constifying types everywhere.
