  1. [M142] [compiler][arm64] Fix Dup and Shuffle recognition

    Original change's description:
    > [compiler][arm64] Fix Dup and Shuffle recognition
    > 
    > The 'dup and shuffle' optimization worked on the assumption that, for
    > swizzles, we could drop the second argument and replace it with the
    > result of the dup. This would result in the dup producing the eight
    > most significant bytes and the canonical shuffle would produce the
    > other eight.
    > 
    > However, because we are dealing with swizzles, it may be that the
    > instruction used to implement the canonical shuffle doesn't read from
    > two registers. In this case the dup is never read and so the top bytes
    > are not what we expect.
    > 
    > Bug: 455592080
