to original benchmark-driver command.
I'm going to add some runner plugins to resurrect metrics which were
originally supported by benchmark/driver.rb...

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/wc.input.base
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.

are using IO#write_nonblock and it's defined in prelude.

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.

the kernel is under memory pressure. Retry sending periodically

any label between `if` and `jump` instructions.

Round up non-zero <1ms timeouts to 1ms and use INT_MAX instead
of infinite (-1) for extremely large timeouts. All of our
ppoll/select callers are able to handle spurious wakeups,
anyways.
This avoids excessive CPU usage and busy waits with short
timeouts to rb_wait_for_single_fd.
CPU usage with the following script is significantly reduced
for systems with "#undef HAVE_PPOLL":
require 'io/wait'
r, w = IO.pipe
Thread.new { loop { r.wait_readable(0.000001) } }.join(5)
exit!(0)
Low-resolution in poll(2) still sucks, though...
Note: I don't see the value in making a similar change to
time_timeval of a <1us sleep is attempted because of GVL
release and syscall latency.

r63655 was tightly coupled to handle_frames and some assumptions seems
to have been broken by r63763.
To partially resolve Bug#14892, this reverts the optimization for now. I
want to make MJIT CI happy first and then I'll probably retry r63655 by
partially reverting r63763 for sp changes.
The skipped test is not fixed yet.
