LingBin 72942ad7a4 Recommit "Avoid adding tombstones of the same file to RangeDelAggregator multiple times" 
Summary:
The origin commit #3635  will hurt performance for users who aren't using range deletions， because unneeded std::set operations, so it was reverted by commit 44653c7b7aabe821e671946e732dda7ae6b43d1b. (see #3672)

To fix this, move the set to  and add a check in , i.e., file will be added only if  is non-nullptr.

The db_bench command which find the performance regression:
> ./db_bench --benchmarks=fillrandom,seekrandomwhilewriting --threads=1 --num=1000000 --reads=150000 --key_size=66 > --value_size=1262 --statistics=0 --compression_ratio=0.5 --histogram=1 --seek_nexts=1 --stats_per_interval=1 > --stats_interval_seconds=600 --max_background_flushes=4 --num_multi_db=1 --max_background_compactions=16 --seed=1522388277 > -write_buffer_size=1048576 --level0_file_num_compaction_trigger=10000 --compression_type=none

Before and after the modification, I re-run this command on the machine, the results of are as follows：

  **fillrandom**
