* Use the longer name ThreadSanitizer rather than TSan for the new files.
* Don't implement `tsan::consume` at all for now.
* Do the `tsan::release` for `ulock_unlock()` at the head of the function,
not at the tail.
* Add a comment to test/Sanitizers/tsan/once.swift to explain the test a
little more clearly.

Move the TSan functionality from Concurrency into Threading. Use it
in the Linux `ulock` implementation so that TSan knows about `ulock`
and will tolerate the newer `swift_once` implementation that uses it.

Moved all the threading code to one place. Added explicit support for
Darwin, Linux, Pthreads, C11 threads and Win32 threads, including new
implementations of Once for Linux, Pthreads, C11 and Win32.
