Most cases seem to be fixed now, gcc.dg/vect/pr33369.c was also reported as
PR95327, testing fix for that.

cc1-cross testing of quite some produce excess errors (missing target libc
headers...).  Still closing as fixed now, please re-open if any FAILs remain.

Those are new ones.  I will track down the source tomorrow morning if no one
else has in the meantime.

    tree-optimization/95273 - more vectorizable_shift massaging

    Covering all bases in vectorizable_shift is hard - this makes sure
    to appropriately handle the case of PR95356 without breaking others.

            * tree-vect-stmts.c (vectorizable_shift): Adjust when and to
            what we set the vector type of the shift operand SLP node
            again.
