auto and size_t in allocator slow paths
Summary:
This shaves a few instructions where we had to zero-extend,
and generally makes it easier to reason about the code without
worrying about 32-bit overflow. Any variable added to a pointer,
or used as an index, already needed to be zero extended anyway.
