Since the conflicts were only an assertion conflicts ([sample](https://github.com/openjdk/jdk/blame/b1e8c4e030f42ea3146b2502c9ab030bc79a8147/src/hotspot/share/gc/shenandoah/shenandoahFreeSet.cpp#L3065)), I'm skipping the complicated backport rabbit hole and picking the latest assertions. The other two backports (8358529, 8373789) are clean.

Is there a need to coalesce all three issues into a single PR? If there are backports in the chain, and they do not break anything when committed one by one, do them one by one. The only (real) reason to do multi-issue PR is when you want to make sure that commit does not break anything.
