- Returns the bit position of the highest bit set in a 32-bit value. Equivalent

-
- This function computes the bit position of the highest bit set in the 32-bit
- value specified by Operand. If Operand is zero, then -1 is returned.
- Otherwise, a value between 0 and 31 is returned.
-
- @param Operand The 32-bit operand to evaluate.
-
- @retval 0..31 Position of the highest bit set in Operand if found.
- @retval -1 Operand is zero.
