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...

by benchmark_driver.gem later.
This commmit changes no benchmark behavior.

`make update-benchmark-driver`, like simplecov.

and adjust arguments for benchmark_driver.gem.

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.

[Feature #14045]
* insns.def (getblockparam, setblockparam): add special access
instructions for block parameters.
getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and
if it is not set this instruction creates a Proc object from
a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
setblockparam is similar to setlocal, but set
VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
* compile.c: use get/setblockparm instead get/setlocal instructions.
Note that they are used for method local block parameters (def m(&b)),
not for block local method parameters (iter{|&b|).
* proc.c (get_local_variable_ptr): creates Proc object for
Binding#local_variable_get/set.
* safe.c (safe_setter): we need to create Proc objects for postponed
block parameters when $SAFE is changed.
* vm_args.c (args_setup_block_parameter): used only for block local blcok
parameters.
* vm_args.c (vm_caller_setup_arg_block): if called with
VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be
a block handler.
* test/ruby/test_optimization.rb: add tests.
* benchmark/bm_vm1_blockparam*: added.

This means File.chmod, File.lchmod, File.chown, File.lchown,
File.unlink, and File.utime operations on slow filesystems
no longer hold up other threads.
The platform-specific utime_failed changes is compile-tested
using a new UTIME_EINVAL macro
This hurts performance on fast filesystem, but these methods
are unlikely to be performance bottlenecks and (IMHO) avoiding
pathological slowdowns and stalls are more important.

This converts all slow syscalls in the Dir.empty? implementation
to release GVL. We avoid unnecessarily GVL release and
reacquire for each slow call (opendir, readdir, closedir) and
instead only release and acquire the GVL once in the common
case.
Benchmark results show a small degradation in single-threaded
performance:

rename(2) requires two pathname resolution operations which can
take considerable time on slow filesystems, release the GVL so
operations on other threads may proceed.
On fast, local filesystems, this change results in some slowdown
as shown by the new benchmark. I consider the performance trade
off acceptable as cases are avoided.

[Feature #13884]
Reduce number of memory allocations for "and", "or" and "diff"
operations on small arrays
Very often, arrays are used to filter parameters and to select
interesting items from 2 collections and very often these
collections are small enough, for example:
```ruby
SAFE_COLUMNS = [:id, :title, :created_at]
def columns
@all_columns & SAFE_COLUMNS
end
```
In this patch, I got rid of unnecessary memory allocations for
small arrays when "and", "or" and "diff" operations are performed.

not for ERB and we should use bm_erb_* for ERB benchmark instead.

to skip object allocation for static string.
We can't always enable frozen_string_literal pragma because we can't
freeze string literals embedded by user for backward compatibility.
So we need to use fstring for each static string.
Since adding ".freeze" to string literals in #content_dump is slow
on compiling, I used unary "-" operator instead.
benchmark/bm_app_erb_render.rb: Added rendering-only benchmark to
test rendering performance on production environment.
This benchmark is created to reproduce the behavior on Sinatra (Tilt).
Thus it doesn't use ERB#result to skip parsing compiled code.
It doesn't use ERB#def_method too to regard `title` and `content` as
local variables. If we use #def_method, `title` and `content` needs
to be method call. I wanted to avoid it.
This patch's benchmark results is:
* Before
app_erb_render 1.250
app_erb 0.704
* After
app_erb_render 1.066
app_erb 0.686
This patch optimizes rendering performance (app_erb_render) without
spoiling (total of rendering +) compiling performance (app_erb).

I was about to write off this benchmark while working on GVL
improvements on multi-core systems.
However I noticed it exposes a weakness in my work-in-progress
code when I tested on an old single CPU system. Further testing
reveals setting CPU affinity ("schedtool -a 0x1" on Linux) on a
modern multi-core system is enough to reproduce the problem
exposed by this benchmark.

"lazy_sweep" does not appear to have ever been a valid kwarg
for GC.start, however the opposite of "lazy_sweep" appears
to be "immediate_sweep". So use immediate_sweep, and flip
the boolean value of each arg.
I guess this only started failing with r56981 in Dec 2016
