I forgot to increase the value of 'i'. It makes the test failures.

I added the 'i' and increased it in new patch. All tests passed.

I have a few comments, but none are about the new for loops themselves.

> Source/WebCore/ChangeLog:8
> +        No new tests, no behavior chnages.

typo

Also, “no behavior change” is not completely a justification for no test coverage; in this case we definitely will tolerate it.

> Source/WebCore/Modules/mediastream/RTCDataChannel.cpp:326
>      events.clear();

This line of code is not needed.

> Source/WebCore/Modules/webaudio/WaveShaperProcessor.cpp:69
> +            WaveShaperDSPKernel* kernel = static_cast<WaveShaperDSPKernel*>(audioDSPKernel.get());

I think we should use a reference and * rather than a pointer and get().

> Source/WebCore/Modules/webdatabase/DatabaseTracker.cpp:723
> +    for (auto& fileName : listDirectory(originPath, String("*.db"))) {

This should either just be "*.db" with no String() or ASCIILiteral("*.db").

> Source/WebCore/Modules/webdatabase/DatabaseTracker.cpp:1226
> +                RefPtr<SecurityOrigin> origin = openDatabase.key;

Strange that this is a RefPtr; no need to ref it. Could just do:

    auto& origin = openDatabase.key;

Or:

    auto& origin = *openDatabase.key;

In the second case we’d have to make a few changes below.

> Source/WebCore/Modules/webdatabase/DatabaseTracker.cpp:1232
> +                for (auto& databaseName : *databaseNameMap) {

I am not sure that the entries in the database name maps are themselves database names.

> +                DatabaseContext* context = database->databaseContext();

No need for a local variable here.

Used the first case.

typedef HashMap<String, DatabaseSet*> DatabaseNameMap;

DatabaseNameMap consists of the 'String' and the 'DatabaseSet'.
Maybe 'String' is the name of databases and 'DatabaseSet' is set of the databases. I changed the 'databaseName' to 'databases'.
It looks like a good name rather than 'databasName'.
How about your idea?
