Hi Nate, thanks for doing this.

> Implement review feedback for vector shuffle work.

    /// VECTOR_SHUFFLE(VEC1, VEC2, SHUFFLEVEC) - Returns a vector, of the same
    /// type as VEC1/VEC2.  SHUFFLEVEC is a BUILD_VECTOR of constant int values
    /// (maybe of an illegal datatype) or undef that indicate which value each
    /// result element will get.  The elements of VEC1/VEC2 are enumerated in
    /// order.  This is quite similar to the Altivec 'vperm' instruction, except
    /// that the indices must be constants and are in terms of the element size
    /// of VEC1/VEC2, not in terms of bytes.
    VECTOR_SHUFFLE,

Ciao,
