It's also useful to know the total cycles of all samples in order to get the cycles coverage for a single program block in further. For example: coverage = per block sampled cycles / total sampled cycles This patch creates a new argument 'total_cycles' in hist__account_cycles(), which will be added with the cycles of each sample.
