[TSan] add a new option 'use_internal_symbolizer' that allows to choose between addr2line-based and llvm-based symbolizer w/o having to rebuild the runtime. This is hopefully a temporary solution that simplifies testing process. In the end, we should leave a single symbolizer.

tsan: remove shutdown code
...
tsan runtime shutdown is problematic for 2 reasons:
1. others crash during shutdown
2. we have to override user exit status (don't know it and can't return from atexit handler)

[tsan] First commit of ThreadSanitizer (TSan) run-time library.
...
Algorithm description: http://code.google.com/p/thread-sanitizer/wiki/ThreadSanitizerAlgorithm
Status:
The tool is known to work on large real-life applications, but still has quite a few rough edges.
Nothing is guaranteed yet.
The tool works on x86_64 Linux.
Support for 64-bit MacOS 10.7+ is planned for late 2012.
Support for 32-bit OSes is doable, but problematic and not yet planed.
Further commits coming:
- tests
- makefiles
- documentation
- clang driver patch
The code was previously developed at http://code.google.com/p/data-race-test/source/browse/trunk/v2/
by Dmitry Vyukov and Kostya Serebryany with contributions from
Timur Iskhodzhanov, Alexander Potapenko, Alexey Samsonov and Evgeniy Stepanov.
