Currently, when -flto=thin is specified, the debug fission option is ignored, we want to enable debug fission with ThinLTO.

There's no need to file bugs for work you're planning to do anyway, if you don't want to (LLVM doesn't have a requirement that patches be attributed to a bug, etc).

Also, to be precise, this is about implicit ThinLTO. Fission is already usable with the explicit backend ThinLTO model.
