[tsan] Use re-exec method to enable interceptors on older versions of OS X
...
In AddressSanitizer, we have the MaybeReexec method to detect when we're running without DYLD_INSERT_LIBRARIES (in which case interceptors don't work) and re-execute with the environment variable set. On OS X 10.11+, this is no longer necessary, but to have ThreadSanitizer supported on older versions of OS X, let's use the same method as well. This patch moves the implementation from `asan/` into `sanitizer_common/`.

Sanitizer: define WIN32_LEAN_AND_MEAN
...
Define WIN32_LEAN_AND_MEAN before including Windows.h. This is already being
done in some places. This does it more broadly. This permits building ASAN on
Linux for Winndows, as well as reduces the amount of included declarations.

Fix ASan's Noinst unit tests
...
We currently skip all "Noinst" unit tests on OS X, which was probably caused when we removed the "allow_reexec" flag. The MaybeReexec function fails to re-execute when the runtime is linked statically, because there is no dylib to use. This patch adds an explicit DisableReexec function that is used from asan_noinst_test.cc and the runtime then doesn't try to re-execute.
