c++: module std and exception_ptr

exception_ptr.h contains

  namespace __exception_ptr
  {
    class exception_ptr;
  }
  using __exception_ptr::exception_ptr;

so when module std tries to 'export using std::exception_ptr', it names
another using-directive rather than the class directly, so __exception_ptr
is never explicitly opened in module purview.

gcc/cp/ChangeLog:

	* module.cc (depset::hash::add_binding_entity): Set
	DECL_MODULE_PURVIEW_P instead of asserting.

gcc/testsuite/ChangeLog:

	* g++.dg/modules/using-20_a.C: New test.
