ruby.git/benchmark/lib, branch ruby_2_6

add small utility for benchmarking.

2018-09-28T03:32:49+00:00

* benchmark/lib/load.rb: add small utility which requires
  benchmark-driver.rb. You can load this file and can
  use benchmark-driver.

output/driver.rb: add output plugin to reproduce

2018-07-10T15:44:45+00:00

the original behavior of benchmark/driver.rb.
Probably I won't use this but this is requested by ko1.

Use this with:
make benchmark OPTS="-o driver"

benchmark_driver/runner: add runners for metrics

2018-07-10T15:01:27+00:00

supported by legacy benchmark/driver.rb.

benchmark/README.md: document them

common.mk: update benchmark_driver to correct 0.0 output and to fix
spacing format of `-o simple` and `-o markdown`.

runner/size.rb: fix metric passed to output

2018-07-10T14:16:57+00:00

runner/peak.rb: ditto

This is needed to make commands like `make -C .ruby-svn benchmark
ITEM=erb OPTS="-r size -o simple"` succeed.

benchmark: resurrect peak / size metrics

2018-07-10T12:14:04+00:00

by adding runner plugins for them.

benchmark/lib/benchmark_driver/runner/peak.rb: added peak runner plugin
benchmark/lib/benchmark_driver/runner/size.rb: added size runner plugin
common.mk: allow using them

benchmark/memory_wrapper.rb: deleted in favor of those runner plugins

benchmark/README.md: document them
