Yep, it is something with the last Richi's patch. Things has worked reosnably
well for me prveiously (through not quite sanely - 94% of WPA time went into
type merging. Good news is that we could hope for really huge speedup fixing
this relatively small part of compiler)
I will try to revert it too and look into inliner dumps on kernel just if I can
spot
something obvious.
