Niels Lohmann e21e3cd1ac Time copies together with their destruction in the benchmarks

Copy timed only the copy and destroyed it with the timer paused, and
Destroy did the reverse. How a document is freed shapes the heap the next
copy allocates from: since the faster destruction (#5762/#5767), part of
its saved work shows up in the next copy's allocations. Copy therefore
looked up to 40% slower than 3.12.0 on glibc although copying and
destroying together got 1.1-1.5x faster.

Copy now times a temporary copy including its destruction. CopyAssign
assigns over an earlier copy, and CopyRing replaces the oldest of eight
live copies. The old benchmarks remain as CopyOnly and DestroyOnly, with
a note that they tell the halves apart but do not compare versions.
