Daniel Dunbar a671c2a9fe Fix (invalid) may-be-uninitialized warning.

Douglas Gregor d01472beee Revert my available_externally vtables experiment. It's breaking the LLVM-with-Clang build with linker errors that I have yet to investigate.

Douglas Gregor 26751ffc53 Silence bogus GCC warning 
llvm-svn: 92787

Douglas Gregor 1a68ab6c83 Make use of available_externally linkage for vtables when the 
non-inline key function of a class template instantiation, when no key
function is present, the class template instantiation itself was
instantiated with an explicit instantiation declaration (aka extern
template). I'm fairly certain that the C++0x specification gives us
this lattitude, although GCC doesn't take advantage of it.

Douglas Gregor 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.

Anton Korobeynikov 73d50b9141 Promote arguments of frameaddr / returnaddr builtins to i32 type, when needed. 
This is needed for the platforms, where bitwidth of "int" is not 32 bits
(e.g. 16 on msp430).

David Chisnall 3a509cd8cc Fix for bug 5691. 
This fixes throwing exceptions inside @catch blocks nested inside outer @try blocks and also fixes jumping from an inner @finally to an outer @finally (via any relevant @catch blocks).

The code exhibiting this bug was based on code from CGObjCMac.  I believe that this bug may still be present on the Mac runtimes, although the test case in the bug contains a few GNUisms and won't compile without some minor tweaks with Apple's libobjc.
