This is done throughout the ASTContext and is not novel here.
We wish to be able to create a new node from a const ASTContext reference.
These creation functions mostly behave const-ish, they just use hash tables in
the ASTContext for caching / identity purposes.
The other alternative is to declare these hash tables as mutable, though this
would necessitate a large noisy change to update everything at once.
