[PATCH] D25417: [libcxxabi] Fix alignment of allocated exceptions in 32 bit builds

EricWF added a comment.

I ran into some test failures on OS X while attempting to commit this. The `unwind.h` header provided on OS X hasn't upstreamed the libunwind fix from  r276215 <https://reviews.llvm.org/D22543>, meaning `__cxa_exception` is still under-aligned and therefore so is the exception.

I'll commit this in the next day or two after dealing with the apple bug.
