Revert "benchmark/.yml: convert from benchmark/bm_.rb" 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 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63926 b2dd03c8-39d4-4d8f-98ff-823fe69b080e 2018-07-10 09:05:29 -04:00			`#!/usr/bin/ruby`
