This reverts commit 67960ba110.
Reason for revert:
This has been properly fixed by https://crrev.com/c/3053740.
Now dcheck_always_on already defaults to false for subprojects
like V8 and no other switch is required. The switch didn't fully
work anyways due to https://crbug.com/1231890.

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.

This includes the simulator, PPC64 Linux (little endian)
and PPC64 AIX (Big endian) running on P9.
Also enable the related simd tests for PPC64.
Qfma opcodes are added to the selector as part of the enablement.

Generic wasm wrappers are enabled by default now (since
https://crrev.com/c/2562241), so we can remove the flag from the
nooptimization variant. Instead, we should have a configuration which
tests --no-wasm-generic-wrapper to find bugs in the compiled wrappers
earlier.
Also add an entry for contradictory flags, and reformat that list to
respect the 80 columns limit.

One of the x86 ISA extensions is confusingly named SSSE3 (*Supplemental*
Streaming SIMD Extensions 3). SSSE3 supersedes SSE3, and is superseded
by SSE4.
This CL adds testing coverage for x86 CPUs that support SSE3
instructions, but do not support SSSE3 instructions. Chrome supports
these CPUs, and they are used by a non-trivial amount of Chrome's users
on Windows. This CL aims to cover all the spots missed by
https://crrev.com/c/2757893.

Simd unsupported in simulator and some machines on mips.
Original Commit Message:
As of https://crrev.com/c/2629465, Simd tests cannot pass on
architectures without Simd support. Tests will need to be
re-enabled once Simd support is fully implemented on PPC.
