everything except linux does not need this hackery with pthread_cond

Summary:
We don't need to do any work in this case - just take
the current PC and caller PC.

currently tsan hangs when linked with a shared library linked against an old version of pthread
this change is another attempt to fix pthread_cond interceptors in different scenarios

Since these are primarily useful for deeply embedded targets where code size is
very important, they are each in a separate file making use of infrastructure
in sync-ops.h. This allows a linker to include just the functions that are
actually used.

[sanitizer] speedup deadlock detector for the case when we destroy a mutex that has never been locked

llvm-svn: 202487

Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.

[sanitizer] do not acquire a global mutex in deadlock detector when dealing with Unlock (it is essentially a thread-local operation)

this fixes obscure false positives

[asan] *experimental* implementation of invalid-pointer-pair detector (finds when two unrelated pointers are compared or subtracted). This implementation has both false positives and false negatives and is not tuned for performance. A bug report for a proper implementation will follow.
