[patch] x86_*fence replaced by membar_ops(3)

Hi lists,

These are the first steps to have MI Xen drivers (hi christoph!), by replacing all the x86_*fence memory ops to their "equivalent" ones from the membar_ops(3) API. See [1].

I took this opportunity to do the same for arch/x86,i386,amd64.

GENERIC/XEN3_DOM0 do compile fine for amd64, and GENERIC/XEN3_DOM0 were compiled and "tested" (through a complete build.sh run) for i386.

@port-xen: what is the purpose of this load fence [2], considering that hypercalls are memory barriers?

Thanks for reading. Comments and reviews are appreciated.
