 // List of all flags in the VM.
 // Flags can be one of three categories:
 // * P roduct flags: Can be set in any of the deployment modes, including in
 //   production.
 // * D ebug flags: Can only be set in debug VMs, which also have assertions
 //   enabled.
 // * R elease flags: Generally available flags except when building product.
 // * pre C ompile flags: Generally available flags except when building product
 //   or precompiled runtime.
