JDK-8259070 - Add jcmd option to dump CDS
Description
JDK-8259070 adds a functionality to jcmd for dumping CDS archive on a running java process.

To reproduce the issue:
1. Start a java app.
2. While the app is still running, use jcmd to create a dynamic CDS archive:
    e.g. jcmd <pid> VM.cmd dynamic_dump
3. Run the app again with the dynamic CDS archive and the -XX:+RecordDynamicDumpInfo option:
    e.g. java  -XX:+RecordDynamicDumpInfo -XX:SharedArchiveFile=java_pid<pid>_dynamic.jsa -cp myApp.jar myApp

C++ standard does not have a define for comparing with NULL, that depends on the language implementor. We should add check before call strcmp just like Windows version.

No hs err log was created for the crash. After debugging the core file, the crash is in: bool os::same_files(const char* file1, const char* file2) { if (strcmp(file1, file2) == 0) { return true; } The file2 being NULL. It was called from Arguments::init_shared_archive_paths() in the following block: if (DynamicDumpSharedSpaces) { if (os::same_files(SharedArchiveFile, ArchiveClassesAtExit)) { vm_exit_during_initialization( "Cannot have the same archive file specified for -XX:SharedArchiveFile and -XX:ArchiveClassesAtExit", SharedArchiveFile); } } Perhaps VM should issue an error and exit if both -XX:+RecordDynamicDumpInfo and -XX:SharedArchiveFile options are specified?
