LLVM has removed llvm::Optional, move over to std::optional. Also

c401cc34fd [Threading] Use llvm::Optional<> rather than making a zero lower bound special.
While most systems aren't going to have their stack bottom at zero,
using llvm::Optional<> here is cleaner.

b5c8b79556 [Threading] Move stack bounds fetching into the threading library.
Fetching the current stack bounds is done using threading functions, so
should be in the threading library.

f3a412dd53 [Threading] Remove thread_get_main().
Removing thread_get_main() means we don't need a static initializer on
Darwin, which means we can delete Darwin.cpp as well.  We can also delete
Nothreads.cpp while we're about it, because there's nothing in that file.

14a4bd45b6 [Concurrency][Threading] Remove use of platform thread functions.
The concurrency library can use the new threading library functions,
which avoids the problem of including <windows.h>.

f5bdb858e0 [Threading] Create new threading library and use 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.
