We ignore cost of MODIFY_EXPR in assumption that it will get quite
likely optimized out (that is important for simple containers).  So
ignoring PHI nodes is consistent in this manner, but on the other hand
PHIs are less often in containers and more likely to stay after
inlining.  I will add code for that.
