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

Dmitry Vyukov e69df1f928 tsan: fix pthread_cond interceptors
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

Tim Northover 1683caab3a ARM: implement __sync_fetch_and_* operations
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.

Evgeniy Stepanov 322e89c4e2 [asan] Install asan_device_setup to bin/ when targetting Android.
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.
