1ca89b8c71 [foozzie] Enable passing extra flags on command line
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.

b3b6b5c655 [foozzie] Ignore error messages in correctness fuzzing
Error messages are unspecified in JavaScript and occasional small
differences in the compared configurations lead to an unjustified
maintenance burden of correctness-fuzzing issues.

This CL replaces most error messages with a fixed suppression
message during correctness fuzzing (behind a flag).

The flag covering all extra behavior for correctness fuzzing is now
renamed to --correctness-fuzzer-suppressions.

ac8c78e01d [cleanup] Replace underscore by minus in d8 flags
Reading --verify_predictable makes me sad, whereas --verify-predictable
makes me happy. This CL introduces more happiness.

0a703c5b93 [foozzie] Disable async compilation of WebAssembly
Async compilation introduces nondeterminism, thus disable it for

47608ce626 [foozzie] Add sanity checks to avoid bug flooding
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.

7315d7b3d7 Preparing v8 to use with python3 /tools
There are now less that 400 days until the end of life
of Python 2(aka _legacy_ Python) https://pythonclock.org/ .
The code compatibility check for python2 and python3
used the following tools: futurize, flake8
You can see the reports here: https://travis-ci.com/bmsdave/v8/builds

605f94b700 [foozzie] Update existing configs for liftoff
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).
