Hi,
I have disabled inliner cache sanity check for profile feedback because profile
count scaling now can cause small roundoff deviations (a cost we had to pay for
dropping separate frequencies I guess). While doing so I missed that the code
block must set current_badness even when not doing any checks.

This fixes the IA64 bootstrap issue reported by Andreas (which is triggered
by his setup using release checking for stage1 cc1).

Bootstrapped/regtested x86_64-linux, comitted.
