15 Returns the value of the highest bit set in a 32-bit value. Equivalent to
18 This function computes the value of the highest bit set in the 32-bit value
19 specified by Operand. If Operand is zero, then zero is returned.
21 @param Operand The 32-bit operand to evaluate.
23 @return 1 << HighBitSet32(Operand)
24 @retval 0 Operand is zero.
