Evgeniy Stepanov 1bc7298c44 [asan] Fix nonsensical reports of partial right OOB. 
In case of partial right OOB, ASan was reporting
  X is located 0 bytes to the right of [A, B)
where X was actually inside [A, B).

With this change, ASan will report B as the error address in such case.

Alexander Potapenko 0be25d562c Check that the FakeStack size is non-zero before looking into it. 
Sometimes DescribeStackAddress is called before another thread's FakeStack is initialized, which could previously cause a check to fire.
