Jason Evans 96d4120ac0 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.
