relative issue: babel/babel-loader#231

rc-component should not use babel-runtime?

@ustccjw 我这个 https://unpkg.com/rc-gesture@0.0.3/dist/rc-gesture.js 没发现 babel-runtime 的冗余代码，只插入了必要的

[ustccjw]

@paranoidjk rc-animate@2.3.6 没使用 babel-runtime 和最新版本可以做比较，不一定是引入冗余代码，只是 core-js 导致体积变大

test with rc-gesture

npm run dist --babel-runtime

generated rc-gesture.js 69.87kB
generated rc-gesture.js.map 89.58kB
generated rc-gesture.min.js 23.67kB

npm run dist

generated rc-gesture.js 23.25kB
generated rc-gesture.js.map 21.93kB
generated rc-gesture.min.js 7.29kB

@paranoidjk 你这个估计模块很少，所以看起来特别显著。不过移动端的项目一般 bundle 不会太大，所以还是有影响的。

helper 冗余了一份， https://babeljs.io/docs/plugins/transform-runtime/#optionshelpers

webpack and babel are effectively broken together because of the babel-runtime issue mentioned above. I suggest trying with the TypeScript compiler instead. I was able to get better output there.
