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.
Tested on x86_64-linux-gnu native, and gcc-14 target riscv{64,32}-elf.
Ok to install?

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
