[vector] Mask and Shuffle construction

[Viswanathan, Sandhya]

Hi Paul,

Efficient optimized implementation for maskFromValues and shuffleFromValue is challenging so we should remove those two methods.

Best Regards,
Sandhya

Hi,

What plans do we have to optimize construction of Mask and Shuffle? i cannot recall where we are on this.

As a summary here are the methods on Species:

  public abstract Mask<E, S> maskFromValues(boolean... bits);
  public abstract Mask<E, S> maskFromArray(boolean[] a, int i);
  public abstract Shuffle<E, S> shuffleFromValues(int... indexes);
  public abstract Shuffle<E, S> shuffleFromArray(int[] a, int i);

Thanks,
Paul.
