7dd7eed65a72a61eea6a6d904094fe8f10ceb512 Revert "add vzeroupper to GCC builds"
This reverts commit 770177dc9ddc0982d27951bc6855d7fb64bb0bd0.
Reason for revert: didn't seem to help, so going back to tabula rasa.
Original change's description:
> add vzeroupper to GCC builds
>
> Turning on the HSW code slice improved performance on Clang
> bots but hurt it on GCC bots. I think it's due to lack of
> vzeroupper, which helps minimize the penalty when switching
> from AVX code back to SSE code. I saw Clang had them in
> exec_ops_hsw()/run_program() in the places you'd expect,
> but GCC did not. This adds one manually in GCC builds.
