Also could you please make a patch to make maybe_hot_count_p to use
hitogram driven cutoff? Otherwise the histograms would be completely
unused for 4.8 and it would be stupid to carry all the extra data
for no use.  I would like this to be done soon, since I plan to base
some of inliner re-tunning to be based on this.

The mismatch is independent problem, yes.
