Kostya Serebryany 0a31ed1417 [tsan] fix the tsan allocator to handle any alignment 
llvm-svn: 164107

Dmitry Vyukov 7e6347402d tsan: fix new memory allocator 
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.
