Currently, when doing degen-cycle, we process references right before immediate-garbage cleanup. It is imperative that we process references before any immediate garbage gets recycled, or else we may end up with bad references during reference-processing. However, the trouble is that immediate garbage can be recycled even before cleanup phase by recycle-assist. For this reason, we must process references before any evacuation during degen GC. It is also more natural: we process refs before weak roots and class-unloading during concurrent cycle, and should do the same during degen cycle.
(Note that we already prevent recycle-assist in concurrent phase)
