AstGen: improved handling of declarations

Browse Source 
* Every decl provides a 16 byte source hash which can be used to detect
   if the source code for any particular decl has changed.
 * Include comptime decls, test decls, and usingnamespace decls in the
   decls list of namespaces.
   - Tests are encoded as extended functions with is_test bit set.
