Allow align argument of GC_memalign to be smaller than pointer size
(fix of commit ba137368d)
This is largely to match the standard requirements on aligned_alloc().
* include/gc/gc.h (GC_memalign): Update comment.
* mallocx.c (GC_memalign): Allow align to be less than a pointer size
(provided it is non-zero).
* mallocx.c (GC_memalign, GC_posix_memalign): Do not expect align
argument is invalid.
