I have an updated patch with some more changes -
1. Renaming cross-lane operations like addAll() to addLanes().
2. Added missing shift*(ByteVector) and rotate*(ByteVector) methods in ByteVector and also in ShortVector.
3. Fixed some issues identified in Javadoc.
4. Fixed the tests and benchmark as per the api changes.

To make the api easy to use, few changes identified are -
1. Rename shift, rotate operations to be more explicit in what they do. Example, shiftL -> shiftLeft. This also follows the convention used in other libraries; example rotateLeft() in java.lang.Integer.
2. Added instance methods in Vector.java to create masks and shuffles. The goal is to help programmers by not having to maintain or acquire a reference to Species when creating masks and shuffle. These methods in turn call the static methods in VectorMask and VectorShuffle with the vector's species.
3. VectorSpecies.boxType() is confusing, rename to vectorType().
4. Add helper method in Species to determine loop terminating condition.
I have created a webrev for these changes. Requesting a review.
