The same option passed to multiple plugins

When multiple plugins require the same option, it's easier to declare it in one place. These options are passed on to two or more plugins.

OptionName	Plugins
keepFnName	Passed to mangle & deadcode
keepClassName	Passed to mangle & deadcode
tdz	Passed to builtIns, evaluate, deadcode, removeUndefined

  "presets": [["minify", {
    "evaluate": false,
    "mangle": true
  }]]
}

{
  "presets": [["minify", {
    "mangle": {
      "exclude": ["ParserError", "NetworkError"]
    }
  }]]
}

{
  "presets": [["minify", {
    "keepFnName": true
  }]]
}
// is the same as

    "mangle": {
