[5.5][Concurrency] Fix the call to swift_task_enqueueGlobal_hook.

mikeash · mikeash · commit ed6520ff7135 · 2021-06-02T16:51:10.000-04:00
We pass swift_task_enqueueGlobal as the original implementation, but that would recurse. We need to pass swift_task_enqueueGlobalImpl instead. rdar://78780136 (cherry picked from commit 70be680)
