Fangrui Song 0170d3c340 [Plugins] Address review comments on -plugin-arg (#227545) ...

Address comments after #226773:

* Accept an empty argument again (-plugin-arg=<plugin>,). Tested by
  tut-simplify-cfg1.ll
* Reject an argument for a name shared by several plugins.
* Remove parsePassPluginCommandLine. Polly and the Bye example, which
  keep cl::opt, call cl::ParseCommandLineOptions from ParseArguments.
* Drop cl::opt from the IRTransforms example: ParseArguments takes v1,
  v2 or v3.
* Test -plugin-arg diagnostics.
