Summary: BlockBasedTableBuilder::ParallelCompressionRep::first_block can be read in Flush() and written in BGWorkWriteRawBlock() concurrently. This commit fixes the issue by reading first_block out before pushing the block to compression and write. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6640 Test Plan: Run all tests concurrently with TSAN.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
