JDK-8224988: Elemental shift and rotate operations speedup
Summary: Patch is having following changes:-
     A) Intrinsification of two vector APIs:
       1) VectorShuffle.shuffleIota(VectorSpecies, int)
       2) VectorShuffle.toVector()
     B) Re-implimentation of following vector APIs using above intrinsified APIs.
       1) Vector.shiftLanesLeft(int)
       2) Vector.shiftLanesRight(int)
       3) Vector.rotateLanesLeft(int)
       4) Vector.rotateLanesRight(int)
