  -----------
  [libc++] Remove unnecessary container constructions in setup code (#216141)

It turns out that a fair amount of the benchmark suite is spent in
unmeasured code. Amongst other things, we were constructing temporary
containers from scratch instead of assigning from an already built-up
copy, which is a lot faster.

This patch speeds up the wall time for running flat_map benchmarks by
approximately 30s (from 98s to 66s) on my machine.
