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

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

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 "; the
problem was not with a missing #include.
