Kuba Brecka bf8b5f8dd2 [tsan] Rename ReportThread->pid to ReportThread->os_id
The field "pid" in ReportThread is used to store the OS-provided thread ID (pthread_self or gettid). The name "pid" suggests it's a process ID, which it isn't. Let's rename it.

Kuba Brecka 06bbca9ec4 [tsan] Add TSan __tsan_atomic* functions to tsan_interface.h
To avoid using the public header (tsan_interface_atomic.h), which has different data types, let's add all the __tsan_atomic* functions to tsan_interface.h.

Kuba Brecka a1496f7c37 [tsan] Add TSan debugger APIs
Currently, TSan only reports everything in a formatted textual form. The idea behind this patch is to provide a consistent API that can be used to query information contained in a TSan-produced report. User can use these APIs either in a debugger (via a script or directly), or they can use it directly from the process (e.g. in the __tsan_on_report callback). ASan already has a similar API, see http://reviews.llvm.org/D4466.

Dmitry Vyukov da6d5b919d tsan: add memory access functions that accept pc
This is required for Java support, as real PCs don't work for Java.

Dmitry Vyukov 312ad250ff tsan: properly instrument unaligned accesses
If a memory access is unaligned, emit __tsan_unaligned_read/write
callbacks instead of __tsan_read/write.
Required to change semantics of __tsan_unaligned_read/write to not do the user memory.
But since they were unused (other than through __sanitizer_unaligned_load/store) this is fine.
Fixes long standing issue 17:

Kostya Serebryany 4ad375f0a9 [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.
