To trigger speculative inlining, a function needs to run a few times on
Liftoff-tier, and then tier-up to Turbofan. We make sure this happens
by enabling --wasm-dynamic-tiering with a small budget, and running
the critical functions until {%IsLiftoffFunction} is false.
We also add an additional test.
