Hiya.

This is looking toward cleaning up a couple of things:

(1) There are 5 bits of x86 host detection, 3 of them for xbzrle.
    Unify this down to one, with additional cleanups for xbzrle.

(2) Provides a host-specific include path for splitting atomic128.h
    and probably other stuff so as to avoid host-specific ifdefs.
    Actually splitting atomic128.h is so far left for further work.
