    tree-optimization/109473 - ICE with reduction epilog adjustment op

    The following makes sure to carry out the reduction epilog adjustment
    in the original computation type which for pointers is an unsigned
    integer type.  There's a similar issue with signed vs. unsigned ops
    and overflow which is fixed by this as well.

            PR tree-optimization/109473
            * tree-vect-loop.c (vect_create_epilog_for_reduction):
            Convert scalar result to the computation type before performing
            the reduction adjustment.

            * gcc.dg/vect/pr109473.c: New testcase.
