9b4f7d62cd Make sure we tail call optimize a call in concurrency runtime's switch_task_impl.
Without this hack the call will leave a stack frame around (not tail
call optimized) and blow the stack if we call switch_task often enough.

Ideally, clang would emit this call as `musttail` but currently it does
not.
