> Current VectorAPI Java side implementation expresses rotateLeft and rotateRight \
> operation using following operations:- 
> vec1 = lanewise(VectorOperators.LSHL, n)
> vec2 = lanewise(VectorOperators.LSHR, n)
> res = lanewise(VectorOperations.OR, vec1 , vec2)
> 
> This patch moves above handling from Java side to C2 compiler which facilitates \
> dismantling the rotate operation if target ISA does not support a direct rotate \
> instruction. 
> AVX512 added vector rotate instructions vpro[rl][v][dq] which operate over long and \
> integer type vectors. For other cases (i.e. sub-word type vectors or for targets \
> which do not support direct rotate operations )   instruction sequence comprising \
> of vector SHIFT (LEFT/RIGHT) and vector OR is emitted. 
> Please find below the performance data for included JMH benchmark.
