    tree-optimization/122747 - fix masking of loops with conditional reduction
ops

    The following amends the earlier fix in r16-5372-gfacb92812a4ec5 to
    also cover the case we're not doing the merge to a single cycle
    but go via vectorizable_call.

            * tree-vect-stmts.cc (vectorizable_call): Handle reduction
            operations that are already conditional.

            * gcc.target/i386/vect-epilogues-10.c: New testcase.
