Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the exception of explicit template instantiations, which have to be weak_odr.

This fixes PR6996.

Add unnamed_addr to vtables.

Just disable the hidden-visibility optimization for now by hiding it behind

a -cc1 option.  The Darwin linker complains about mixed visibility when linking
gcc-built objects with clang-built objects, and the optimization isn't really
that valuable.  Platforms with less ornery linkers can feel free to enable this.

Emit weak vtables of non-template classes with hidden visibility.

Improve key-function computation for templates. In particular:

2010-01-05T19:06:31+00:00

  - 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.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.

2009-12-15T20:14:24+00:00

 - This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

It's OK to try to emit a vtable definition more than once. Fixes PR5697.
