git-node: `git node bisect`

https://twitter.com/targos89/status/982158028878196736

Outline:

• git node bisect --from 20180101 [--to 201810406] /path/to/test.js
• Detect the right arch, then download correct binaries from https://nodejs.org/download/nightly/ , decompress it, run the test with bin/node, bisect until it finds two consecutive nightlies where the exit code of the test becomes different
  • Let the user configure where the files are downloaded via ncu-config set tmpdir, default can be .ncu/tmp or /tmp
• Grab the sha from the nightlies, suggest the user to run:
  • git bisect start <nightly1-sha> <nightly2-sha> --
  • git bisect run "make -j8 && ./node /path/to/test.js"

首先检查 node-core-utils 现有的 CLI 入口点，以及对 ncu-config set tmpdir 的配置处理；该 issue 未指定具体的文件或测试。查看 Node.js nightly 的下载布局和提议的 git bisect 命令。当 git node bisect 工作流能够选择架构、下载并运行 nightly、确定退出代码的变化，并建议相应的 Git 命令时，即视为完成。
