Avoid NULL check in free() and malloc_usable_size(). Generalize isalloc() to handle NULL pointers in such a way that the NULL checking overhead is only paid when introspecting huge allocations (or NULL). This allows free() and malloc_usable_size() to no longer check for NULL. Submitted by Igor Bukanov and Mike Hommey.
