Currently, probabilities for extra flags are calculated in the correctness
fuzzer harness, which makes the RNG fragile when bisecting backwards, when
the script's config changes during bisection.
This adds the possibility to pass extra flags on command line to the
script. After a grace period, we will migrate the flag calculation to
clusterfuzz.

We have too many dupes in the no-ic comparisons. We'll increase the
experiment size again once bugs are fixed.

This lets foozzie call d8 with sanity output before doing the actual
correctness comparisons. This will make clusterfuzz dedupe cases on
the difference found in the sanity checks.
Also adding missing OWNERS file.

Instead of having a separate liftoff config, which is tested against
the default (which currently means tier-up from liftoff to turbofan),
just choose reasonable liftoff configs for the existing configs.
'ignition' now implies pure liftoff execution.
'ignition_turbo_opt' always compiles with turbofan.
Other configs use the default (tier up).

This adds 5% testing of 'ignition' vs 'liftoff', which tests Turbofan vs
Liftoff for wasm code, and tests Ignition vs Turbofan for javascript
code.
It also adds 3% testing of 'liftoff' (x64) vs 'liftoff' (ia32), which
does standard x64 vs ia32 testing for javascript code.

We'll soon also host other configurations for general fuzzing, not only
correctness fuzzing in the new tools/clusterfuzz folder.
