Remove it outright for Standard `discard_block_engine` (via the new base class `_Discard_block_base`), `independent_bits_engine`, and `shuffle_order_engine`. For `discard_block`, which is usually the base class for Standard `discard_block_engine`, we can guard the typedef with TR1's availability, and deprecate it. We should then avoid using it ourselves.
…scard_block_base`. `discard_block_engine` had an `_Engine&&` constructor but its base classes didn't, so it was always copying.
