Yes. However, for now, I am not enabling support for `cls64` on ARM32 as it is
not done yet.

ACLE does provide a `long long` version of `cls` called `__clsll`. But since
the support for `cls64` on Arm32 is not done yet, I decided not to write
support for `__clsll`. If I did, it would work for 64-bit but not for 32-bit.
Please let me know what you think.
