6a84889d3f Replace the class offset vectors in RecordLayoutBuilder with maps instead so we'll have faster lookup and so we can detect duplicates.

c3015a914f Allocate ASTRecordLayout objects using the allocator associated with ASTContext. 
This allows them to be allocated using a BumpPtrAllocated
in the common case.

aef662206b Patch removes IVars list from ObjCInterfaceDecl and 
instead relies on their DeclContext for iteration, etc.

0a2754ed8a Be sure to select primary bases among the nearly empties in preorder, 
not just among the direct bases.  Before we where missing nearly
empties that were bases of virtual base classes.

a318efd1f2 Improve key-function computation for templates. In particular: 
- 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.

f98849eb8a In Sema, whenever we think that a function is going to cause a vtable to be generated, we mark any virtual implicit member functions as referenced.

96d5c76498 Added rudimentary C++0x attribute support. 
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)
