Count Leading Zeros.
where:
cond
Rd
Rm
The CLZ instruction counts the number of leading zeros in the value in Rm and returns the result
in Rd. The result value is 32 if no bits are set in the source register, and zero if bit[31] is set.
Do not use SP and do not use PC.
This instruction does not change the flags.
CLZ{cond} Rd, Rm
