Yeah, the captions are a bit misleading, sorry for that. 
What it shows is the preprocessing time for all of Phoenix with partially
preprocessed headers (using PP) and without (no PP).

Definitely, but the point was to see improvements in the preprocessing phase
as the compilation phase is independent of this.
