RFR: 8255784: appcds/javaldr/ExceptionDuringDumpAtObjectsInitPhase.java test failed resulting in VM crash

[Yumin Qi]

Please review this simple change.
  The crash is caused by vm_exit_during_initialization which calls vm_exit, the latter will go check vm shutdown procedures. The shutdown checks thread and lock state, finds inconsistent state so the check fails. Here we could just use vm_direct_exit with some message as the process terminated.  vm_direct_exit just calls os::exit which quits without generating a coredump.

Tests: tier1-4

Thanks
Yumin
