    vect: Do not peel epilogue for partial vectors.

    r14-7036-gcbf569486b2dec added an epilogue vectorization guard for early
    break but PR114196 shows that we also run into the problem without early
    break.  Therefore merge the condition into the topmost vectorization
    guard.

    gcc/ChangeLog:

            PR middle-end/114196

            * tree-vect-loop-manip.cc (vect_can_peel_nonlinear_iv_p): Merge
            vectorization guards.

    gcc/testsuite/ChangeLog:

            * gcc.target/aarch64/pr114196.c: New test.
            * gcc.target/riscv/rvv/autovec/pr114196.c: New test.
