Most of the "noise" (in terms of line-count) are the FAILs that are
not LTO exclusive because we run for all of the torture options
(IMHO a bit excessive).

Btw, it seems that nobody files bugs / triages guality regressions
which means we could as well remove the guality as a whole (it's
slow anyway).
