SWIFT_STDLIB_SINGLE_THREADED_RUNTIME is too much of a blunt instrument here. It covers both the Concurrency runtime and the rest of the runtime, but we'd like to be able to have e.g. a single-threaded Concurrency runtime while the rest of the runtime is still thread safe (for instance). So: rename it to SWIFT_STDLIB_SINGLE_THREADED_CONCURRENCY and make it just control the Concurrency runtime, then add a SWIFT_STDLIB_THREADING_PACKAGE setting at the CMake/build-script level, which defines SWIFT_STDLIB_THREADING_xxx where xxx depends on the chosen threading package. This is especially useful on systems where there may be a choice of threading package that you could use. rdar://90776105
