Sorry, by "everywhere" I meant "on every architecture" (even though it's technically architecture-dependent whether int64_t is `long` or `long long`, but I think the latter should still work for both). Of course I was only talking about this function, the 32-bit clz() should still use the 32-bit builtin.
