nodemon - change files on disk that really changed

[normalser]

Similar to #8660 but probably different.
Is it possible for tsc to only "replace/modify" files on disk if they really got changed.
I understand that entire project needs to be "compiled" but it would be great if only changed 'js' files on disk would be overwritten.
Otherwise it creates issues with tools like nodemon - it picks up change in first file - restarts, then another file - restarts, etc ... - for now I need to put delay in nodemon config - which is not the best approach.

Really more a duplicate of #3204 which has been pushed to TS2.1.

This is already handled by #3113. it should be available in typescript@next. please give it a try and let us know if you are still running into issues.

closing in favor of #3113
