According to the second hw intrinsic API review meeting https://github.com/dotnet/apireviews/tree/master/2018/Hardware-Intrinsics-Intel, we need to change some intrinsic APIs and their implementation

  1. Redesign SSE4.2 STTNI intrinsic
  2. 64-bit only intrinsics
  3. Improve StaticCast
    1. exploding frequently-used intrinsic on more base-types Add all integer overloads for AlignRight/BlendVariable and unsigned overloads for MultiplyLow coreclr#19420
    2. move StaticCast and some other helpers into vector classes, and rename StaticCast to As.
  4. New intrinsic requests
  5. Missing and incorrect APIs
  6. Remove generic Intel hardware intrinsic and explode them on all the supported types
