In order to migrate the extra flags into the fuzzer and keep bisection stable,
we need to use the same RNG state for each call to generating fuzz flags.
Throughout one fuzzing session the same random-seed is used
(https://crbug.com/983128) and we'll pass it to the fuzz config in a follow up.

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

This replaces the "trusted" with the "jitless" correctness-fuzzing experiment.
The former is a no-op already.

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.
