It allows using NonNMethod code space for method handle intrinsics which are needed urgently if the other code cache spaces are full. There are other options (see JBS issue), but this one appears to be the simplest one.

Those are reasonable suggestions.  Sounds like a plan.  For this PR, could you refactor the oops checking logic into its own method?  Then would it make sense to add checks for relocations that use metadata?  Some types of call sites are resolved lazily, so they could be using metadata without that being reflected in the oops.
