_aligned_malloc() on Windows first takes size, then alignment, which is the opposite of how the similar function behaves on Linux. Memory allocated by it also has to be freed using _aligned_free(), unlike Linux where we can use regular free().

Edit aligned_alloc() macro and add a aligned_free() one to align with the above behaviour.
