This is a preparation CL to enable actually sharing JIT'ed code between isolates within the same isolate group. We start with conservative settings, disabling various compiler optimisations. We will lift those restrictions step-by-step. Since this is guarded by FLAG_enable_isolate_groups it will not affect any production code. Only individual tests which opt-in via the flag. TEST=Existing tests opt'ing into --enable-isolate-groups.
