[0.21.0] Some 3rd-party plugins are not able to get correct/full vendor.js content

[jfcherng]

Recently I am playing with brotli-webpack-plugin but I found that the generated pre-compressed vendor.HASH.js.br does not contain the content of _tmp_shared.HASH.js.

After searching in the source codes, I found that the content of _tmp_shared.HASH.js is appended to vendor.HASH.js at the very last second (the done compiler hook). But the brotli-webpack-plugin (and many other webpack plugins?) hooks on the emit compiler hook so it just never gets the correct/full source.

Ideally, "appending _tmp_shared.HASH.js to vendor.HASH.js" should be performed earlier?

Yes, that makes sense - I can't immediately think of a reason why we shouldn't append the content earlier.
