A recent change caused a performance regression. This restores the previous performance and adds a performance test. * scripts/check_performance: Allow tests to choose a -std flag. * src/c++17/memory_resource.cc (bitset::get_first_unset()): Use local variables of the right types. Call update_next_word() unconditionally. * testsuite/20_util/unsynchronized_pool_resource/cons.cc: New test. * testsuite/performance/20_util/memory_resource/pools.cc: New test. * testsuite/util/testsuite_performance.h (time_counter): Allow timer to be restarted.
