tuklib_integer: Use __builtin_clz() with Clang.

Clang has support for __builtin_clz(), but previously Clang would
fallback to either the MSVC intrinsic or the regular C code. This was
discovered due to a bug where a new version of Clang required the
<intrin.h> header file in order to use the MSVC intrinsics.

Thanks to Anton Kochkov for notifying us about the bug.
