This reverts r63900.
Having single-execution benchmark as a normal Ruby script is preferred
by ko1. I'm not a big fan of having inconsistent benchmark formats, but
I can understand some benefits of it.
common.mk: remove obsolsted benchmark-each PHONY declaration, support
running Ruby scripts added by this commit.
README.md: follow ARGS change

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

During instruction translation (linked list -> iseq generation), we can
treat `TS_VALUE` and `TS_ISEQ` the same as they are just embedded in the
generated sequences. The only difference between `TS_ISE` and `TS_IC`
is that an inline storage entry may contain a markable `VALUE` pointer
at some point, so we need to flag the iseq as containing markable
objects.

Objects loaded during iseq deserialization using arrays need to be added
to the compile time mark array so that they stay alive until iseqs
finish loading.

in favor of just using benchmark_driver.gem.
common.mk: The new `make benchmark` covers the both usages for old `make
benchmark` and old `make benchmark-each`. So `make benchmark-each` is
dropped now.

POSIX mmap(3) manpage stipulates mmap bumps the reference
count of the file description. Thus keeping a file descriptor
to maintain the reference is not necessary.
If this didn't work, every extension .so would require a
permanent FD, which is obviously not the case.

When measured script is really too fast, while loop substituion may
return a negative benchmark result.
Probably benchmark_driver.gem has rooms to be improved about this.

benchmark/driver.rb had removed the cost for while loop in benchmark/bm_vm1_*.rb,
and benchmark_driver.gem can achieve the same thing with `loop_count`.
But unfortunately current benchmark_driver.gem can't solve it only for vm1_yield.yml...

This YAML transformation is needed to support whileloop2 time substituion
by benchmark_driver.gem later.
This commmit changes no benchmark behavior.

Makefile.in: Clone benchmark-driver repository in benchmark/benchmark-driver
`make update-benchmark-driver`, like simplecov.
win32/Makefile.sub: Roughly do the same thing.
.gitignore: Ignore the cloned repository.
common.mk: Trigger `make update-benchmark-driver` to run `make benchmark`
and adjust arguments for benchmark_driver.gem.
benchmark/require.yml: renamed from benchmark/bm_require.rb, benchmark/prepare_require.rb
benchmark/require_thread.yml: renamed from benchmark/bm_require_thread.rb, benchmark/prepare_require_thread.rb
benchmark/so_count_words.yml: renamed from benchmark/bm_so_count_words.rb, benchmark/prepare_so_count_words.rb,

benchmark/so_k_nucleotide.yml: renamed from benchmark/bm_so_k_nucleotide.rb, benchmark/prepare_so_k_nucleotide.rb,
benchmark/make_fasta_output.rb
benchmark/so_reverse_complement.yml: renamed from benchmark/bm_so_reverse_complement.rb, benchmark/prepare_so_reverse_complement.rb,
benchmark/make_fasta_output.rb
I'm sorry but I made some duplications between benchmark/require.yml and benchmark/require_thread.yml,
and between benchmark/so_k_nucleotide.yml and benchmark/so_reverse_complement.yml.
If you're not comfortable with it, please combine these YAMLs to share
the same prelude. One YAML file can have multiple benchmark definitions
sharing prelude.
benchmark/driver.rb: Replace its core feature with benchmark_driver.gem.
Some old features are gone for now, but I'll add them again later.

It seems like they are all benchmark drivers but "benchmark/driver.rb"
is the latest and others are no longer used.
It's confusing to have multiple drivers (and actually I used
benchmark/run.rb since I didn't know I should use benchmark/driver.rb).
As I'm going to support only benchmark/driver.rb features in Misc#14902,
let me delete them.

Any single object allocation can reduce object count, and
object counts are global, so multi-threading leads to unpredictable
results.

pthread_atfork is not idempotent and repeatedly calling it
causes it to register the same hook repeatedly; leading to
unbound memory growth.
Ruby already has a (confusing-named) internal API for to call
in the forked child process: rb_thread_atfork
Call the MJIT child_after_fork hook inside that to prevent
unbound growth with the following loop:
loop do
RubyVM::MJIT.pause
RubyVM::MJIT.resume
end

We need to preserve "IGNORE" behavior from Ruby 2.5 and earlier.
We can't rely on SA_NOCLDWAIT any more, since we always need
system() and MJIT to work; so we fake that behavior using
dedicated reaper (currently in timer-thread).

Non-parallel "make test-spec" caused
spec/ruby/core/process/wait2_spec.rb failures because mspec
uses "exec" in single-process mode, so there's no chance
the post-exec state could know about the MJIT child process
from its pre-exec state.
