Kostya Serebryany 4a9187a810 call __asan_load_cxx_array_cookie when loading array cookie in asan mode. ...

Summary:
The current implementation of asan cookie is incorrect:
we add nosanitize metadata to the cookie load, but the metadata may be lost
and we will instrument the load from poisoned memory.
This change replaces the load with a call to __asan_load_cxx_array_cookie (r216692)
