    Several implementations were essentialy a common piece of C code using
    the cmpxchg() macro.  Put the implementation in one spot that everyone
    can share, and convert sparc64 over to using this.
    Alpha is the lone arch-specific implementation, which codes up a
    special fast path for the common case in order to avoid GP reloading
    which a pure C version would require.
