    tree-optimization/121059 - fixup loop mask query

    When we opportunistically mask an operand of a AND with an already
    available loop mask we need to query that set with the correct number
    of masks we expect.

            PR tree-optimization/121059
            * tree-vect-stmts.cc (vectorizable_operation): Query
            scalar_cond_masked_set with the correct number of masks.

            * gcc.dg/vect/pr121059.c: New testcase.
