ZGC crashes on GraalVM 21

[leomc2005]

Describe the issue

After changing gc from G1 to ZGC, we started to observe VM crashes.
The problematic frames have different causes, apparently related to truffle compiled nmethod.
The logs are attached.

Run JVM with the following arguments: -XX:+UseZGC -XX:InitiatingHeapOccupancyPercent=70 -XX:ReservedCodeCacheSize=512m -Dsun.reflect.inflationThreshold=2147483647 -XX:MaxVectorSize=16
