During the investigation of JDK-8292088, the question was raised if Opaque2 nodes are really useful anymore today. A closer analysis suggested that they are not fulfilling their original purpose anymore. This RFE should investigate if Opaque2 nodes could be completely removed (together with reorg_offsets()) by backing it up with some benchmark results.
We could re-investigate in a separate RFE if it is worth to re-implement reorg_offsets() in a way that fulfills its original purpose to lower register pressure.
