The verbose output shown on bots didn't print the first failing result
of a flaky test before. Now the result line shows all results and
the details in the end show the output of the first failure.
Previously it was confusing as it seemed that the json results and
the test runner output differed.
We now print PASS in all caps like the other statuses. A test for
this case already existed and the output is now updated.

This changes the test runner to automatically treat cases in which
both a flag and its negation are present as a flag contradiction.
Example: "--foo --no-foo".
With this change it's no longer necessary to explicitly specify these
trivial contraditions in variants.py.
Note: since negations are created through simple string operations,
bogus constructions are possible ("--nobodys-perfect" ->
"--bodys-perfect"). We accept these as unlikely-to-cause-problems.

This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.
The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.
The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

We used to recompile WasmCapiCallWrappers whenever they were
needed, but never garbage-collected them, which caused a memory
leak when many short-lived instances of the same module were
created. This patch makes the wrappers cacheable and caches them,
which avoids both repeated compilation effort and the unbounded
memory growth.
Drive-by cleanup: unify WasmCapiFunctionData with the other
Wasm*FunctionData classes by making it inherit from WasmFunctionData.

tldr: This adds an on-demand comparison with x64 when a difference to
a non-x64 build is detected.
Normally foozzie compares the baseline build (just ignition), with
two secondary builds. One, the default, always uses the shipping
configuration, the second passes additional flags. Both can use a
different architecture than the baseline build as well.
Differences between ignition and turbofan are then often detected
independent of the architectures used, but reported several times
(for each compared architecture).
This makes the reporting more specific, by running another build on
demand that uses the baseline architecture, but otherwise the same
configuration that showed a difference. If it shows the difference as
well, the baseline architecture is used for the report.
As a result only pure architecture differences will be reported with
an architecture other than x64.
This also adds some minor refactorings to reduce the code complexity
when looping over comparisons.
For testing this, the fake-d8s are extended with different behavior
for different flags passed. We add two test cases for testing:
x64 vs. ia32 with difference in x64 and ia32
x64 vs. ia32 with difference only in ia32

This is a reland of 6c65e858a6
Changes since revert:
- Add --disable-shared-ro-heap-for-testing flag that is implied by
d8's --stress-snapshot, since RO heap sharing currently
does not support deserializing/serializing while original Isolate
is still running
- Add BUILD.gn assert that v8_enable_pointer_compression_shared_cage
requires x64 or arm64
