library), the change is generic and you want it to be merged. 
Will this be merged to the repos of GDC and DMD, or if you want 
to do a generic change, do you have to use the DMD repo?

Another question, do we need LDC to have own repos for the 
compiler and library. Would it possible to use the DMD submodules 
and then have the LDC extras in an specific LDC submodule?

One uses the most generic repo, i.e., upstream DMD, and has to 
wait for the change to trickle down to LDC and GDC (or, if it's 
super-important, open a PR with backported fix).

We don't just have some extra files but touch upstream files in 
all of these repos. We only use parts of the DMD repo; the 
frontend is a direct part of the ldc repo (`dmd` subdir), while 
DMD's `test` dir is the base for our dmd-testsuite repo/submodule.
