	* typemanager.cs (IsCLRType): New routine to tell whether a type
	is one of the builtin types.

	Maybe it needs to use TypeCodes to be faster.  Maybe we could use
	typecode in more places instead of doing pointer comparissions.
	We could leverage some knowledge about the way the typecodes are
	laid out.

	New code to cache namespaces in assemblies, it is currently not
	invoked, to be used soon.

	* decl.cs (DeclSpace.MakeFQN): Simple optimization.

	* expression.cs (Binary.ResolveOperator): specially handle
	strings, and do not perform user-defined operator overloading for
	built-in types.
