Reid Kleckner d483c072af sanitizers: Make sure Visual Studio gets error reports 
Visual Studio appears to close stderr before launching a non-console
win32 program.  This means we don't see any sanitizer reports.  If
stderr printing fails, call OutputDebugStringA to get the reports into
the Visual Studio debugger console.

Dmitry Vyukov e2391f66f9 tsan: fix linking when -ltsan is passed before -lpthread 
libpthread is weird:
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000b9b0 T pthread_cond_init@@GLIBC_2.3.2
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000c720 T pthread_cond_init@GLIBC_2.2.5
let's do it with @@ for now
we can always introduce more macros parameters later

Sergey Matveev 69931c5841 [sanitizer_common] Add internal_clone(). 
Add a wrapper for the clone syscall for use in StopTheWorld. We
implement it only for x86_64, so stop building StopTheWorld for other platforms
(no one uses it outside x86_64 anyway).

See https://code.google.com/p/address-sanitizer/issues/detail?id=214 for why we
can't use the glibc clone() wrapper.
