[Bug middle-end/17667] New: Const/pure function detection during tree-based profiling

Jan Hubicka said:

the problem is caused by tree profiling affecting const/pure function
autodetection resulting in CFG missmatch in between profiling and
feedback passs.  As disucssed with Rth, all the alternatives of fixing
this I can think of seems nasty and bit invasiave for 4.0. [...]

This should be revisited for 4.1
