Fix ObjC++ interop bug.
...
The reworked wrapping of C++ exceptions meant that we were missing a
dereference of the result of __cxa_begin_catch.
Add a test that triggers this issue. It would have occurred in the
non-ARC version if we actually did anything with the exception, but
compiling it in ARC mode makes the compiler insert retain / autorelease
around the exception object to ensure that it remains live.

Rework Objective-C++ exceptions.
...
The new version now does not depend on the layout of the C++ exception
structure and instead finds the two offsets that it cares about.

If an exception unwinds to the top of a thread, the process will die, so
don't worry about leaking memory for this case.

Fix a bug in ObjC++ EH.
...
Throwing an Objective-C exception through a C++ catch block was broken.
This was because the C++ code inserts a cleanup handler to make sure
that it invokes `__cxa_end_catch`. Unwinding through this catchup
transformed the Objective-C exception into a C++ one. This case should
have been handled, except for two bugs:
1. A typo (`#ifdef` instead of `#ifndef`) meant that we were not
extracting the Objective-C exception from the C++ object.
2. We were skipping everything except catchalls after the search phase,
because we lose some information in the transformation.

Implemented the new exception ABI, and a load of tests for it. This is used by
...
clang trunk if -fobjc-runtime-1.7 is specified and provides significantly
better interoperability with foreign exceptions.
Note: Most of the exception tests will not pass with gcc or clang < 3.3. They
test things that are impossible to implement quite correctly with the
GCC-compatible exception ABI.
Also updated the release notes to reflect recent improvements.

More EH tweaks. New ABI now uses "@id" for id catches and NULL for catchalls. Code compiled with GCC and clang with the old ABI will continue to use NULL for catchalls and id catches, which means that C++ exceptions will be caught in their boxed form here and must be explicitly rethrown.

45c428f9a3
Allow the boxed exception object to rethrow itself, if it knows how. This means that a C++ function can throw a C++ object, we can box it in an ObjC object for passing through Objective-C stack frames, and then unbox it to catch it in C++ code.
