Get the batches skip intermediate results would have merged

On a queue without skip_intermediate_results, the batches the option would have merged on a later batch's pass instead of waiting for their own checks, by intervals of time: how many there were, how long in total they went on waiting, in seconds, until their own checks ended or something else ended them, how many of those checks failed, making the batches tested on top of them run theirs again, and how many did not merge as they were. Each batch is counted in the interval its wait ended.
