Select a strategy to mitigate speculative execution attacks (e.g., SPECTRE).
The accepted values are:
None - No mitigations are used in JIT compiled code.
AllTargets - All branches are protected against speculative attacks.
This has a significant performance impact.
GuardTargets - Only branches that preserve Java memory safety are protected.
This has less performance impact than AllTargets.
NonDeoptGuardTargets - GuardTargets except that branches which deoptimize are not
protected since they can not be executed repeatedly.

Where IdealGraphVisualizer graph dumps triggered by Dump or DumpOnError should be written.
The accepted values are:
File - Dump IGV graphs to the local file system (see DumpPath).
Network - Dump IGV graphs to the network destination specified by PrintGraphHost and PrintGraphPort.
If a network connection cannot be opened, dumping falls back to file dumping.
Disable - Do not dump IGV graphs.
