// 1) Trial inline f => g1 => h.
// 2) Make f => g1 call site polymorphic by calling f => g2.
// This gets rid of the ICScript::inlinedChildren_ edge.
// 3) Restore f => g1.
// 4) Trigger a shrinking GC from f => g1 => h (h not trial-inlined; h preserves Baseline code)
// This purges h's inlined ICScript.
// 5) Call f => g1 => h (trial inlined). This must not use the discarded ICScript.
