BUG! There is an E2 in the namespace N, this is an unscoped enum.
LLDB does have the enum type:
(lldb) p e
(N::E) $0 = E1
(lldb) p N::E::E2
(int) $1 = 1
So the problem seems to be that we don't form the correct AST from the debug
information here, in particular that the DeclContext of the namespace isn't
getting the names for the enumerators inserted into it.
