[PATCH] libstdc++: Make it possible to annotate the shared pointer operations in the std::thread implementation

Subject: [PATCH] libstdc++: Make it possible to annotate the shared pointer operations in the std::thread implementation

As documented in the libstdc++ manual, the shared pointer operations in
libstdc++ headers can be instrumented by defining the macros
_GLIBCXX_SYNCHRONIZATION_HAPPENS_BEFORE()/AFTER() and libstdc++ has to be
rebuilt in order to instrument the remaining shared pointer operations.
However, rebuilding libstdc++ is inconvenient. So let's move the thread
wrapper code from thread.cc into <thread>.

* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51504.
