    [snapshot] enable mksnapshot usage to be displayed · c8679386
    Daniel Bevenius authored
    Currently, when specifying '--help' with mksnapshot it will only
    print the v8/d8 help message and options and then exit the process.
    This means that the usage message from mksnapshot will never be
    displayed.
    
    This commit suggests adding an option to SetFlagsFromCommandLine that
    can disable this printing and exiting. This allows mksnapshot to display
    the usage and print the options after that.
    
    While this works, it does seems a little strange that
    SetFlagsFromCommandLine prints the help message and exits the process
    but I'm probably missing some background details around this.
