This fixes the helper creating invalid RTLIL when called with is_signed set to true.
See here from the commit message:
Only the B input (the shift amount) can be marked as signed on a $shiftx cell. Adapt the helper accordingly and prevent it from creating invalid RTLIL when called with is_signed set. Previously it would mark both A and B as signed.
If applicable, please suggest to reviewers how they can test the change.
There's no way to test this without writing external code, I think.
