This transformation replaces the body of _getMainClosure in dart:_builtin with `return main` for the script's main if there is one and removes the body if there is no main. Without this transformation fasta will compile `return null` and dartk will compile `return throw new NoSuchMethodError...`. Both of these patterns will be patched in the VM when dart:_builtin is compiled from Kernel. BUG= R=sigmund@google.com Review-Url: https://codereview.chromium.org/2861023002 .
