Benchmark for Swift's async/await in a special variation.
Note that:
- In those tests, the factor between async calls and non-asyncs call is quite low in most cases (near 1).
- But there are three cases where this factors is quite high (~ 227, ~ 42, and ~ 6703). (In debug mode, only the last one is much higher than one, ~ 22).
