expressions in a function or class template.
This patch makes the following changes:
- Create a DependentScopeDeclRefExpr for the default argument instead of
a CXXDependentScopeMemberExpr.
- Pass CombineWithOuterScope=true so that the outer scope in which the
enum is declared is searched for the instantiation of the enum.
