instantiation, to ensure that we mark class template specilizations as
abstract when we need to and perform checking of abstract classes.
Also, move the checking that determines whether we are creating a
variable of abstract class type *after* we check whether the type is
complete. Otherwise, we won't see when we have an abstract class
template specialization that is implicitly instantiated by this
declaration. This is the "something else" that Sebastian had noted
earlier.

common to both parsing and template instantiation, so that we'll find
overridden virtuals for member functions of class templates when they
are instantiated.
Additionally, factor out the checking for pure virtual functions, so
that it will be executed both at parsing time and at template
instantiation time.
These changes fix PR5656 (for real), although one more tweak
w.r.t. member function templates will be coming along shortly.
