      Description

      In the process of removing the VerifyOpto flag (JDK-6394013) it was unclear if the following line should be removed in PhaseIdealLoop::split_if_with_blocks_post() in looptopts.cpp:

      1437 if (!x->is_Load() && !x->is_DecodeNarrowPtr()) _igvn._worklist.yank(x);

      This needs some further investigation how a removal affects optimization.
