[vm/concurrency] As preparation step to sharing JITed code, disable various optimizations

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.
