The memory_limit_hits doesn't go well with the other names in the
view. Can we consider memory_exceeded_count? I find
memory_exceeded_count (or memory_exceeds_count) more clear and
matching with the existing counters. Also, how about keeping it
immediately after slot_name in the view? Keeping it in the end after
total_bytes seems out of place.
