6bdc484fd8 Added Equal method to Comparator interface
Summary:
In some cases, equality comparisons can be done more efficiently than three-way
comparisons. There are quite a few places in the code where we only care about
equality. This patch adds an Equal() method that defaults to using the
Compare() method.

Test Plan: make clean all check

242b9769c3 Memtablerep Benchmark
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
