The zlib source we DEPS in for testing has been patched with x86 optimizations, some requring SSE2, some SSE4.2, and some PCLMULQDQ (between SSE4.2 and AVX). Might as well turn them on? zlib actually boils everything down into one do-we-have-everything bit. That's a little weird... I don't see any real reason not to use fill_window_sse() on a machine with SSE2 but not SSE4.2. Whatever. While tweaking libpng settings is really where it's at to make PNG encoding faster, this is kind of a nice little cherry on top. Won't help people who are using their own zlib, of course.
