Protect more algorithms from overloaded comma operators
* include/bits/stl_algo.h (__find_if_not_n, generate_n): Cast to void
to ensure overloaded comma not used.
* include/bits/stl_algobase.h (__fill_n_a, equal): Likewise.
* include/bits/stl_uninitialized.h (__uninitialized_fill_n)
(__uninitialized_fill_n_a, __uninitialized_default_n_1)
(__uninitialized_default_n_a, __uninitialized_copy_n)
(__uninitialized_copy_n_pair): Likewise
* testsuite/20_util/specialized_algorithms/memory_management_tools/1.cc:
Use test iterator wrappers with overloaded comma operator.
* testsuite/25_algorithms/fill_n/1.cc: Likewise.
* testsuite/25_algorithms/generate_n/1.cc: New test.
* testsuite/25_algorithms/stable_partition/1.cc: New test.
* testsuite/util/testsuite_iterators.h (operator,): Add deleted
non-member comma operator with iterator wrappers as right operand.
