Upgrade AlignedMemory to support dynamic allocations.
Adds two new methods: AlignedAlloc and AlignedFree for creating and
destroying dynamic aligned allocations respectively. Also adds a
helper class, ScopedPtrAlignedFree, for use with scoped_ptr_malloc.
AlignedAlloc uses posix_memalign for OS X (now that we're targeting
10.6), Linux and _aligned_alloc() on Windows. Android and NaCl use
memalign() since they do not expose posix_memalign() and memalign()
is safe to use with free() on those platforms.
Also hacks around a bug in Visual C++ where __alignof will sometimes
return zero:
