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).
