If CDS dump time and runtime have the same modules settings, e.g., we have the same values for the following options between dump time and runtime:

    --module-path
    --upgrade-module-path
    --add-modules
    --limit-modules
    --add-exports
    --add-reads
    --patch-module

(or, as a simplified case, none of the above options were given in dump time or run time), we can re-use the module graph computed at dump time. I.e., the bootLayer returned by ModuleBootstrap::boot():
