            Bug ID: 241639

           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Enhancement

As Yusuke suggested in https://github.com/WebKit/WebKit/pull/1523#pullrequestreview-1006702442, Map / Set methods can be moved to JSGlobalObject's fields.
Also, we can go further and drop JSC::call and invoke C++ functions like mapProtoFuncValues directly, or even manipulate JSMap directly.

Sam suggested in https://github.com/WebKit/WebKit/pull/1523#issuecomment-1156653410 that we might not need backing Map / Set at all, as it merely duplicates data in most cases given DOM C++ code usually already had a HashMap or HashSet backing things.
