Fix memory barrier support on icc on ia64, 2nd attempt.

hlinnaka · hlinnaka · commit e5592c61adb0 · 2013-07-09T11:34:18.000+03:00
Itanium doesn't have the mfence instruction - that's a 386 thing. Use the
"mf" instruction instead.

This reverts the previous commit to add "#include &lt;emmintrinsic.h&gt;"; the
problem was not with a missing #include.
