Tag TypeObjects which wrap a value with ScalarTypeObject

Capturing this type of objects has a nice side-effect of being
able to specialize code generation. It is furthermore useful
for providing a common definition of getValue() method.

This is an unfortunate side-effect of changing the API
mapping for boolean typedefs: the accessor changes from isValue()
to getValue().
