There is a commonly used library that interposes the write call, and is interposed itself. When running with `TSAN_OPTIONS=verbosity=(1|2)`, this leads to a thread locking itself, resulting in the program hanging. This patch adds a new flag `lock_during_write` to TSan (on Apple platforms only) that, when set, allows interceptors to be bypassed during calls to write. The flag can be inherited by children, or not, depending on the value. rdar://157565672
