vec_rsqrte() on IBM Power 9 64-bit - VSX
Purpose: Returns a vector containing estimates of the reciprocal square roots of the corresponding elements of the source vector.
Result value: Each element of output contains the estimated value of the reciprocal square root of the corresponding element of a.
Endian considerations: None.
Notes: For finite square roots, this intrinsic guarantees at least 14 bits of accuracy.
