since apparently _aligned_malloc requires freeing with _aligned_free and:
/* Defined if gomp_aligned_alloc doesn't use fallback version
and free can be used instead of gomp_aligned_free. */
#define GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC 1
so the second condition isn't satisfied. For uses inside of the OpenMP
allocators we can still use _aligned_malloc but we need to call _aligned_free
in gomp_aligned_free.

* libgomp.h (GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC): Don't define for
defined(HAVE__ALIGNED_MALLOC) case.
* alloc.c (gomp_aligned_alloc): Move defined(HAVE__ALIGNED_MALLOC)
handling as last option before fallback instead of first.
(gomp_aligned_free): For defined(HAVE__ALIGNED_MALLOC) call
_aligned_free.
