vec_addc_u128: Vector Add Compute Carryout unsigned 128-bits
d = vec_addc_u128(a, b)Gets the carry bit of the 128-bit addition of two quadword values.
This function operates on the vectors as 128-bit unsigned integers. It returns the carry out of a + b.
If there is a carry on the addition, the 127-bit of d is set to 1, otherwise 0. All other bits of d are 0.
