98ca79435a Introduce CodeGenModule::GetTargetTypeStoreSize() to calculate the store size 
of LLVM types in character units.

55bcea1e65 Generalize target weirdness handling having proper layering in mind: 
1. Add helper class for sema checks for target attributes
 2. Add helper class for codegen of target attributes

As a proof-of-concept - implement msp430's 'interrupt' attribute.

5866fe306d Fix for PR5967: Make const-marking for LLVM globals correct for cases requiring 
run-time initialization, and emit run-time initializers aggresively to avoid
ordering issues with deferred globals.

2a34df3264 Fix linkage for RTTI names by re-using the logic for computing the 
linkage of vtables. Before this, we were emitting RTTI names for
template instantiations with strong external linkage rather than with
weak ODR linkage.

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.

8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable

e949e6cced Mangler: Lift shouldMangleDeclName predicate out of CXXNameMangler::mangle. 
- 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.

e128dd18ab IRgen: Switch the C++ mangler interfaces to take the SmallVector to write into,

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)

49ddc5fb94 Make GetAddrOfConstantStringFromLiteral return a constant of the correct type. 
This doesn't have any visible effects at the moment because normally the
implicit cast code forces the type to the expected type.

b7e5c847c4 Implement proper linkage for explicit instantiation declarations of 
inlined functions. For example, given

  template<typename T>
  class string {
    unsigned Len;

  public:
    unsigned size() const { return Len; }
  };

  extern template class string<char>;

we now give the instantiation of string<char>::size
available_externally linkage (if it is ever instantiated!), as
permitted by the C++0x standard.
