    tree-optimization/110571 - fix vect_need_peeling_or_partial_vectors_p

    The following avoids re-calling of vect_need_peeling_or_partial_vectors_p
    after peeling.  This was neccesary because the function does not
    properly handle being called for epilogues since it looks for the
    applied prologue peeling not in the main vector loop but the current
    one operated on.

Remove.

            Fix when called on epilog loops.  Make static.
