C++ PATCH for c++/78690 (ICE with using and global type with same name)

We entered type_dependent_object_expression_p considering an
IDENTIFIER_NODE, which is always dependent.  But because there's a
global type with the same name, the identifier had global_type_node as
its type, which isn't recognized as a dependent type.  Fixed by
handling IDENTIFIER_NODE directly.

Tested x86_64-pc-linux-gnu, applying to trunk.
