anand76 d795a730be Combine data members of IOStatus with Status (#9549) 
Summary:
Combine the data members retryable_, data_loss_ and scope_ of IOStatus
with Status, as protected members. IOStatus is now defined as a derived class of Status with
no new data, but additional methods. This will allow us to eventually
track the result of FileSystem calls in RocksDB with one variable
instead of two.

Benchmark commands and results are below. The performance after changes seems slightly better.

```./db_bench -db=/data/mysql/rocksdb/prefix_scan -benchmarks="fillseq" -key_size=32 -value_size=512 -num=5000000 -use_direct_io_for_flush_and_compaction=true -target_file_size_base=16777216```

```./db_bench -use_existing_db=true --db=/data/mysql/rocksdb/prefix_scan -benchmarks="readseq,seekrandom,readseq" -key_size=32 -value_size=512 -num=5000000 -seek_nexts=10000 -use_direct_reads=true -duration=60 -ops_between_duration_checks=1 -readonly=true -adaptive_readahead=false -threads=1 -cache_size=10485760000```
