bench: Add tests for constructing various containers from iterator. Both "bound" (like, length known) and "unbound" (length unknown) are tested. All of list, tuple, bytes, bytesarray offer approximately the same performance, with "unbound" case being 30 times slower. 2014-06-20 02:44:33 +08:00			`import bench`
