[Committed, testsuite] Fix PR92870
With my recent commit, I added a test that is not passing on all targets.
My change was valid for targets that have a vector/scalar shift/rotate optabs
(optab that supports vector shifted by scalar).
Since it does not seem to be easy to find out which targets would support it,
I am limiting the test to the targets that I know pass.
