I've tried bootstrap with -flto-partition=none and also get differences in
gengtype and cc1, so it seems to be unrealated to partitioning change. First
bigger one is:

So it seems to be something else than partitioning changes. Looking at
assembly there are some things that seems like partitioning&inlining
differences. This partiuclar one doesn't seem to be.
