int impala::MemPool::ChunkInfo::allocated_bytes

bytes allocated via Allocate() in this chunk

int impala::MemPool::ChunkInfo::cumulative_allocated_bytes

number of bytes allocated via Allocate() up to but excluding this chunk; not valid for chunks > current_chunk_idx_ (because that would create too much maintenance work if we have trailing unoccupied chunks)
