Muir Manders 749a5cd4ad gopls/internal/regtest: fix completion benchmarks
I fixed a check in sandbox.go to check for size of config.Files
instead of nilness. The completion benchmarks run with an absolute
path workdir and were failing this check due to a non-nil but empty
config.Files.

I tweaked the benchmark output so it is compatible with benchstat. In
particular, the benchmark output now appears all on one line for an
imaginary benchmark named BenchmarkStatistics.

I also made a couple changes to the completion benchmarks:
- Don't modify the buffer before every completion. Type checking
  completely dominates completion, so if it has to type check every
  time then you aren't benchmarking the completion code at all.
- Don't try to exclude GC from the benchmark. I think amortized GC
  time should be included in the benchmark timing. Plus, I'm not sure
  that forcing a GC every 10 iterations was actually doing a good job
  excluding GC from the benchmark.
