template instantiations with strong external linkage rather than with
weak ODR linkage.

Fix marking of virtual members for nested classes whose first non-pure virtual function has a body inlined in the class

llvm-svn: 92855

  - All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

 - Sometimes we have to mangle things we wouldn't normally (e.g., because they appear in a template expression).

 - This also tidies up the predicate to be more obvious what is getting mangled.

The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)

This doesn't have any visible effects at the moment because normally the
implicit cast code forces the type to the expected type.

we now give the instantiation of string<char>::size
