r=me with just a nitpick.

> +    auto textureTypeIndex = std::find(m_textureTypeNames, m_textureTypeNames + WTF_ARRAY_LENGTH(m_textureTypeNames), nativeTypeDeclaration.name()) - m_textureTypeNames;

I understand that is more concise, but I am not entirely comfortable with replacing some reasonable code by pointer arithmetic (the - m_textureTypeNames at the end).
It gets me especially wary because of the auto. Is this std::ptrdiff_t ?uintptr_t ?
