    aarch64: Fix expansion of svsudot [PR114607]

    Not sure how this happend, but: svsudot is supposed to be expanded
    as USDOT with the operands swapped.  However, a thinko in the
    expansion of svsudot meant that the arguments weren't in fact
    swapped; the attempted swap was just a no-op.  And the testcases
    blithely accepted that.
