fix C implementation of a_clz_32
this broke mallocng size_to_class on archs without a native
implementation of a_clz_32. the incorrect logic seems to have been
something i derived from a related but distinct log2-type operation.
with the change made here, it passes an exhaustive test.
as this function is new and presently only used by mallocng, no other
functionality was affected.
