    Add prototype declarations of functions in lib/clz_ctz.c. These
    functions are required by GCC builtins and hence can not be removed
    despite of their unreferenced appearance in kernel source.

    This eliminates the following warning in lib/clz_ctz.c:

    lib/clz_ctz.c:16:12: warning: no previous prototype for `__ctzsi2' [-Wmissing-prototypes]
    lib/clz_ctz.c:22:12: warning: no previous prototype for `__clzsi2' [-Wmissing-prototypes]
    lib/clz_ctz.c:44:12: warning: no previous prototype for `__clzdi2' [-Wmissing-prototypes]
    lib/clz_ctz.c:50:12: warning: no previous prototype for `__ctzdi2' [-Wmissing-prototypes]

    Some architectures need __c[lt]z[sd]i2() for __builtin_c[lt]z[ll] and
    that causes a build failure. They can be implemented using the
    fls()/__ffs() and overridden by linking arch-specific versions may not
    be implemented yet.

    This is required by "lib: add lz4 compressor module".
