Fix size value wrap around in AO_malloc_large

AO_malloc(SIZE_MAX) should return NULL now.

* src/atomic_ops_malloc.c (SIZET_SAT_ADD): New macro.
* src/atomic_ops_malloc.c (AO_malloc_large): Use SIZET_SAT_ADD to
avoid integer overflow when computing the memory size to map (i.e.,
malloc should handle arguments close to SIZE_MAX correctly).
