Daco Harkes 0cd55a18c1 [vm] Introduce cachable idempotent calls ... Adds a `CachableIdempotentCallInstr` that can be invoked via `@pragma('vm:cachable-idempotent')` if the call-sites is force optimized. The object pool is not visited by the scavenger. So, we store the results as unboxed integers. Consequently, only dart functions that return integers can be cached. Cachable idempotent calls should never be inlined. After the first call the function not be called again. The call itself is on a slow path to avoid register spilling on the fast path.
