Ignore statements not working correctly for barrel/index files

As the title states, I found an issue with ignore statements in barrel/index files that just re-export other modules. Coverage gets reported incorrectly and the ignore comments actually add statements to the file. Also, I think /* c8 ignore file */ would be nice 😊

Example repo: beyerleinf/c8-barrel-test - just run npm t and open coverage/index.html.

I don't believe this behavior was ever implemented in v8-to-istanbul.

In case it matters, I just noticed that this also happens for files that only contain interfaces - which is pretty annoying 😄
