[kvm-unit-tests PATCH v3 1/7] lib: Drop x86/processor.h's barrier() in favor of compiler.h version

[Sean Christopherson <seanjc@google.com>]

Drop x86's duplicate version of barrier() in favor of the generic #define
provided by linux/compiler.h.  Include compiler.h in the all-encompassing
libcflat.h to pick up barrier() and other future goodies, e.g. new
attributes defines.
