[14] RFR(S): 6394013: C2: Remove VerifyOpto

[Vladimir Kozlov]

Hi Christian

I am not sure about removing code in loopopts.cpp. Yes, comment have to 
be adjusted but we need investigate more how removing this code can 
affect optimization.
The issue here is not false-positive report from VerifyOpto but that 
optimization could be undone.
We do run _igvn.optimize() at the end of each loop opts iteration.

Thanks,
Vladimir
