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.

[Sanitizer] Switch the symbolization strategy that would be used by sanitizer tools family: as compiling in-process symbolizer into runtime involves certain difficulties, we may instead launch an external symbolizer program (fork + execl) in a subprocess and communicate with it via pipe.

[Sanitizer] Wrapper around llvm::DIContext from LLVM DebugInfo library. If a macro SANITIZER_USES_LLVM_LIBS is defined (by default it is not), then sanitizer runtime includes llvm headers and tries to use LLVM libs for in-process symbolization. To make it functional, we have to link with these LLVM libs - either pass them to linker from Clang driver, or link them into static ASan runtime when we build it.
