Alexey Samsonov b3053d9cbe Allow UBSan+MSan and UBSan+TSan combinations (Clang part). 
Embed UBSan runtime into TSan and MSan runtimes in the same as we do
in ASan. Extend UBSan test suite to also run tests for these
combinations.

Alexey Samsonov 56d6fc81a5 Introduce tsan_cxx and msan_cxx libraries (compiler-rt part). 
For now tsan_cxx and msan_cxx contain only operator new/delete
replacements. In the future, when we add support for running UBSan+TSan
and UBSan+MSan, they will also contain bits ubsan_cxx runtime.

Dmitri Gribenko 9cbc6f42aa Revert r230171 "TSan runtime: unbreak the build with ccache" 
It broke a buildbot with a non-clang (?) compiler.

Alexey Samsonov 03499e920b [Sanitizer] Change the runtime flag representation. 
This mirrors r225239 to all the rest sanitizers:
ASan, DFSan, LSan, MSan, TSan, UBSan.

Now the runtime flag type, name, default value and
description is located in the single place in the
.inc file.

Dmitry Vyukov bde4c9c773 tsan: refactor storage of meta information for heap blocks and sync objects 
The new storage (MetaMap) is based on direct shadow (instead of a hashmap + per-block lists).
This solves a number of problems:
 - eliminates quadratic behaviour in SyncTab::GetAndLock (https://code.google.com/p/thread-sanitizer/issues/detail?id=26)
 - eliminates contention in SyncTab
 - eliminates contention in internal allocator during allocation of sync objects
 - removes a bunch of ad-hoc code in java interface
 - reduces java shadow from 2x to 1/2x
 - allows to memorize heap block meta info for Java and Go
 - allows to cleanup sync object meta info for Go
 - which in turn enabled deadlock detector for Go

Alexey Samsonov 5716928ae2 [TSan] Build TSan-instrumented version of libcxx and use it in lit tests. 
TSan can produce false positives in code that uses C++11 threading,
as it doesn't see synchronization inside standard library. See
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-February/035408.html
for an example of such case.

We may build custom TSan-instrumented version libcxx to fight with that.
This change adds build rules for libcxx_tsan and integrates it into
testing infrastructure.
