Hmmm, this still doesn't look right, some Solaris versions have this, some
don't. Furthermore, the #ifdefs are out of sync with AlignedFree below.

The right way to fix this would be adding #defines for HAVE__ALIGNED_MALLOC,
HAVE_MEMALIGN, and HAVE_POSIX_MEMALIGN to v8config.h, including the selection
logic. Autotools anyone...? :-D

   // posix_memalign is not exposed in some Android versions, so we fall back to
   // memalign. See http://code.google.com/p/android/issues/detail?id=35391.
   ptr = memalign(alignment, size);
