Mateusz Guzik 34c538c356 malloc: try to use builtins for zeroing at the callsite
Plenty of allocation sites pass M_ZERO and sizes which are small and known
at compilation time. Handling them internally in malloc loses this information
and results in avoidable calls to memset.

Instead, let the compiler take the advantage of it whenever possible.
