    [testsuite] [riscv] xfail some [PR113281] tests

    Some of the tests regressed with a fix for the vectorization of
    shifts.  The riscv cost models need to be adjusted to avoid the
    unprofitable optimization.  The failure of these tests has been known
    since 2024-03-13, without a forthcoming fix, so I suggest we consider
    it expected by now.  Adjust the tests to reflect that expectation.
