Mac bot errors are due to issues with wpt server (see bug 158137) and are unrelated to this patch.

This code should use the new local variable, frame.

> Source/WebCore/loader/cache/CachedResourceLoader.cpp:1015
> +void CachedResourceLoader::incrementRequestCount(const CachedResource& res)

Should rename "res" to "resource" when touching this code.

I don't think m_font is guaranteed to not be null.

This should be made into a c++11-style forloop.

If m_font is null, status is set to Success and load() will not be called.
But I agree it may be easy to break that assumption.
I will add an ASSERT(m_font).

Should use auto.

> Source/WebCore/loader/ResourceLoader.cpp:63
> +    : m_frame(&frame)

m_frame should be a Ref instead a RefPtr, I think

> Source/WebCore/loader/ResourceLoader.cpp:68
>      , m_identifier(0)
>      , m_reachedTerminalState(false)

>      , m_cancellationStatus(NotCancelled)

Should initialize these scalars in the header instead of here. Same for m_resourceType and m_isQuickLookResource.

Thanks for both reviews.
Except for m_frame which currently needs to be a RefPtr, I integrated all feedback.
