Assume `__cxa_allocate_exception` returns an under-aligned memory on
Darwin if the version of libc++abi isn't new enough to include the fix
in r319123
This patch resurrects r264998, which was committed to work around a bug
in libc++abi that was causing _cxa_allocate_exception to return a memory
that wasn't double-word aligned.

In addition, this patch makes clang issue a warning if the type of the
thrown object requires an alignment that is larger than the minimum
guaranteed by the target C++ runtime.
