780077f6d1 [test-runner] Move test case processing beyond the multi-process boundary.
This will allow moving the test outcome check beyond the
multi-process boundary in a follow up. It'll allow wrapping
more complex test jobs like predicable mode on the multi-
process side, which will make the code easier to maintain.

This loads all test suites and status files to catch subtle

f39d1cd4aa [test] Switch off perf data feature on swarming.
The feature sometimes prevents subsequent swarming bots to
delete the work directory on windows.

The data file is not kept on swarming bots anyways, therefore
this switches off the feature completely.

fb9ad89fea [Interpreter]: Add ignition blacklist to mjsunit.status and test262.status.
Adds a blacklist of tests which are currently unsupported or broken in Ignition to
the mjsunit and test262 test status.

Also removes --ignition-script-filter flag, and adds a
--ignition_fallback_on_eval_and_catch flag which fallsback to fullcodegen for
functions which call eval or contain a catch block.

efcc7fb2bd [Swarming] Let test runner exit gracefully after test failures.
The flake detection is done on the infra-side according to
the contents of the json test results. We don't want the
runner to fail after flakes.

This was controlled on the infra side by accepting any exit
codes so far. After the swarming switch, this is more
difficult, because the runner is wrapped by the swarming
collect script. There, failing exit codes can mean many
things, including network failures. Therefore, we now
force exit code 0 with test failures if those failures
are reported in the formal test results json.

The infrastructure will take care of reporting the flakes
and failures accordingly.

366dc81143 [Swarming] Presort tests - slowest first.
Swarming won't support an incremental data file. By just
sorting the lowest hanging fruits to the beginning we
already get a big bang for the buck (>80% of the improvement
we get otherwise).

This will require semi-regular manual updates of the
slowest tests.

9516dccd41 Reland "[test] Fix cctest path separators on Windows"
Now run-tests.py understands "suite/foo/bar" with forward slashes for
command-line test selection on all test suites on all platforms.

Previously, file-based suites like mjsunit also accepted "mjsunit/foo\bar";
that behavior is sacrificed here in favor of unification. For the cctest
suite, OTOH, it wasn't possible on Windows to select specific tests at all.

This updates the test runner to run all tests in both sloppy
and strict mode.

It also marks the test in the status file as failing in
sloppy mode even if all it does is marking the test as
[PASS, FAIL]. A future CL will have to validate that the
tests pass and fail in the correct mode.

fbe973ff17 [test] Refactoring - Use subject/observer pattern for progress indicators.
This should prevent bugs caused by missing super calls in
overridden methods. The assumption is that methods of
different indicators are independent.

f41a81b8a5 [test] Refactoring - Let runner handle test IDs.
This prepares for properly rerunning tests. Currently when
tests are rerun, the same test object is reused. This
will be changed in a follow up.

a2b6dfb2d1 [test] Correctly merge expected test outcomes.
Without this change, wildcards always overwrite the outcomes
of more specific rules. Now we always merge.

e81ee90018 [test] Limit "unittests" suite to default variant.
This changes the unittests suite to be run in only the default variant,
because unit tests are (and should be) written to be independent from
global flags.
