An unaligned atomic bug was unfortunately introduced in #119 because the `bytesWritten` field was placed at the end of the `chunkedContentCoder` struct. This places this after the bytes.Buffers and the bool causing it to be misaligned. The ideal placement of this variable is not entirely clear but placing it before the progresiveWrite bool should help. An alternative would be to just place this atomic field at the top of the struct then there would be no risk of it becoming misaligned in future. I moved a few things around to reduce the size of the struct too but it could be possible to adjust things a little more to make the struct a little smaller.

The newly introduced stats in the PR #1702 and #117
are currently computed all time the irrespective of whether or not its needed. Since it is in a fairly hot code path, it could affect the performance when these stats are not needed. Hence, this PR aims to hide those stats computation behind a flag which controls the same.
