Vignesh Balasubramanian 4ec2bad744 Updating reduction step of AVX512 DNRM2 API
- Updated the final reduction of partial sums to use scalar accumulation
  entirely, instead of using the _mm512_reduce_add_pd( ... ) intrinsic.
  This will in turn change the associativity and the rounding-off
  pattern in the reduction step.

- Defined a union data-type to do the same, by having a 512-bit
  register and a double-precision array as its members.

- Updated the declaration and usage of the register variable according
  to the union definition, for uniformity.
