Summary: Make RocksDb build and run on Windows to be functionally
complete and performant. All existing test cases run with no
regressions. Performance numbers are in the pull-request.
Test plan: make all of the existing unit tests pass, obtain perf numbers.

[noticed a new warning when building with the very latest gcc]
* db/memtablerep_bench.cc (FLAGS_env): Remove declaration
of unused varaible, to avoid this warning/error:
db/memtablerep_bench.cc:135:22: error: ‘FLAGS_env’ defined but not\
used [-Werror=unused-variable]

Summary:
Create a benchmark for testing memtablereps. This diff is a bit rough, but it should do the trick until other bootcampers can clean it up.
Addressing comments
Removed the mutexes
Changed ReadWriteBenchmark to fix number of reads and count the number of writes we can perform in that time.
Test Plan:
Run it.
Below runs pass
./memtablerep_bench --benchmarks fillrandom,readrandom --memtablerep skiplist
./memtablerep_bench --benchmarks fillseq,readseq --memtablerep skiplist
./memtablerep_bench --benchmarks readwrite,seqreadwrite --memtablerep skiplist --num_operations 200 --num_threads 5
./memtablerep_bench --benchmarks fillrandom,readrandom --memtablerep hashskiplist
./memtablerep_bench --benchmarks fillseq,readseq --memtablerep hashskiplist
--num_scans 2
./memtablerep_bench --benchmarks fillseq,readseq --memtablerep vector
