Summary: This diff adds a new ticker stat, NUMBER_ITER_SKIP, to count the number of internal keys skipped during iteration. Keys can be skipped due to deletes, or lower sequence number, or higher sequence number than the one requested. Also, fix the issue when StatisticsData is naturally aligned on cacheline boundary, padding becomes a zero size array, which the Windows compiler doesn't like. So add a cacheline worth of padding in that case to keep it happy. We cannot conditionally add padding as gcc doesn't allow using sizeof in preprocessor directives.
