  7. ENH, SIMD: Discard non-signaling comparison intrinsics 

      Providing non-signaling comparison intrinsics that guarantee
  no FP invalid exception in case of qNaN sounds great but it
  cost unacceptable extra intrinsics on  ppc64le(VSX) and x86(SSE).

  Therefore, an integer definition #NPY_SIMD_CMPSIGNAL has been
  provided instead to differenate between SIMD extensions
  that support only supports signaling comparison.
