zlib is a codebase with a long history, and at its core it does not
have a good way to do such things quite.
we've tried to avoid making core structural changes, and instead tried
to stick with the local style

in that light ;-)
most of the improvements are generic, not x86 specific... meaning even
on some other cpu these patches should
give you quite a boost in performance. The x86 bits give additional
gain obviously...
