  Changed paths:
    M compiler-rt/lib/scudo/standalone/primary64.h

  Log Message:
  [scudo] Support partial concurrent page release in SizeClassAllocator64

After extracting memory groups, it's safe to do
1. markFreeBlocks
2. releaseFreeMemoryToOS concurrently with pushBlocks() and
popBatches(). This will improve the throughput of Scudo.
