    middle-end: rejects loops with nonlinear inductions and early breaks
[PR113163]

    We can't support nonlinear inductions other than neg when vectorizing
    early breaks and iteration count is known.

    For early break we currently require a peeled epilog but in these cases
    we can't compute the remaining values.

    gcc/ChangeLog:

            PR middle-end/113163
            * tree-vect-loop-manip.cc (vect_can_peel_nonlinear_iv_p):
            Reject non-linear inductions that aren't supported.
