Fix PR c++/60573
PR c++/60573
* name-lookup.h (cp_binding_level): New transient field defining_class_p
to indicate whether a scope is in the process of defining a class.
* semantics.c (begin_class_definition): Set defining_class_p.
* name-lookup.c (leave_scope): Reset defining_class_p.
* parser.c (synthesize_implicit_template_parm): Use cp_binding_level::
defining_class_p rather than TYPE_BEING_DEFINED as the predicate for
unwinding to class-defining scope to handle the erroneous definition of
a generic function of an arbitrarily nested class within an enclosing
class.
PR c++/60573
* g++.dg/cpp1y/pr60573.C: New testcase.
