/// The implementation of the global executor when not using Dispatch but

/// the functions here are called.
///
/// This file is included into GlobalExecutor.cpp only when both
/// Dispatch integration and the cooperative global executor are disabled.
/// It is expected to define the following functions:
/// swift_task_asyncMainDrainQueueImpl
/// swift_task_checkIsolatedImpl
/// swift_task_donateThreadToGlobalExecutorUntilImpl
/// swift_task_enqueueGlobalImpl
/// swift_task_enqueueGlobalWithDeadlineImpl
/// swift_task_enqueueGlobalWithDelayImpl
