The interpreter is not an execution tier in production any more. It's only used in tests. Thus, remove {ExecutionTier::kInterpreter} and instead add a {TestExecutionTier} that still has {kInterpreter}. If needed (in {TestingModuleBuilder::execution_tier()}), we translate back from {TestExecutionTier} to {ExecutionTier} (for {kLiftoff} and {kTurboFan} only). The {TraceMemoryOperation} method, which is shared between interpreter and production code, now receives a {base::Optional<ExecutionTier>}, and we will just pass en empty optional if called from the interpreter.
