My only comment is that we should be careful regarding compile time 
overhead and not computing information that we do not need.

On the other side, I am fine with adding this now and possibly tuning
this down later on.

Johannes, please have a look at compile time changes that are reported 
at llvm.org/perf after your commit.

Cheers,
Tobias
