[jdk21u-dev] RFR: 8317809: Insertion of free code blobs into code cache can be very slow during class unloading [v2]

[Goetz Lindenmaier]

> Big change, but only two resolves needed:
> 
> src/hotspot/share/gc/g1/g1ConcurrentMark.cpp
> The context differs because "8309538: G1: Move total collection increment from Cleanup to Remark"
> is only in 22
> 
> src/hotspot/share/gc/serial/genMarkSweep.cpp
> Resolved adding an #include.
> 
> SAP nightly testing passed.
