RFR: 8364558: Test compiler/startup/StartupOutput.java failed with native OOM: CodeCache: no room for StubRoutines

[Andrew Dinn]

This PR avoids bringing down the VM when a code cache allocation for the stubgen compiler blob is requested by the compiler thread and fails because the code cache is full. Instead the VM is allowed to carry on with the compiler disabled.

 - Handle failed compiler blob allocate gracefully
