770177dc9ddc0982d27951bc6855d7fb64bb0bd0 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.
