Subject: ASTNodes use MemoryArena (#1376)

* Add a ASTBuilder to a Module
Only construct on valid ASTBuilder (was being called on nullptr on occassion)

* Add nodes to ASTBuilder.

* Compiles with RefPtr removed from AST node types.

* Initialize all AST node pointer variables in headers to nullptr;

* Initialize AST node variables as nullptr.
Make ASTBuilder keep a ref on node types.
Make SyntaxParseCallback returns a NodeBase

* Don't release canonicalType on dtor (managed by ASTBuilder).

* Give ASTBuilders a name and id, to help in debugging.
For now destroy the session TypeCache, to stop it holding things released when the compile request destroys ASTBuilders.

* Moved the TypeCheckingCache over to Linkage from Session.

* NodeBase no longer derived from RefObject.

* Only add/dtor nodes that need destruction.
First pass compile on linux.
