[test] Enable test status filtering by variant This adds the possibility to address test cases in the status file with the variant under which the test is running. This is only allowed in top-level sections. Example: [{ 'test-case': [PASS, SLOW], }] ['variant == foo', { 'test-case': [FAIL], }] The test case "test-case" is marked as slow in all variants. Additionally, in variant foo, it'll be expected to fail. This CL also exemplifies the new feature with test cases running under the ignition_turbofan variant. The corresponding legacy flag is deprecated. BUG=v8:5238 Review-Url: https://codereview.chromium.org/2203013002 Cr-Commit-Position: refs/heads/master@{#38342}

Decouple the --ignition from the --turbo flag. Both Ignition and TurboFan have been enabled by default for a while. This just disentangles the implication between those two flags and sets the --ignition individually. They can now be controlled individually.

Use --opt instead of --crankshaft in tests. 1. Replaces --crankshaft with --opt in tests. 2. Also fixes presubmit to check for --opt flag when assertOptimized is used. 3. Updates testrunner/local/variants.py and v8_foozie.py to use --opt flag. This would mean, nooptimize variant means there are no optimizations. Not even with %OptimizeFunctionOnNextCall.

[wasm] Initial signal handler This is basically the minimum viable signal handler for Wasm bounds checks. It includes the TLS check and the fine grained instructions checks. These two checks provide most of the safety for the signal handler. Future CLs will add code range and data range checks for more robustness. The trap handling code and data structures are all in src/trap-handler, with the code that actually runs in the signal handler confined to src/trap-handler/signal-handler.cc. This changes adds a new V8 API that the embedder should call from a signal handler that will give V8 the chance to handle the fault first. For hosts that do not want to implement their own signal handler, we include the option to install a simple one. This simple handler is also used for the tests. When a Wasm module is instantiated, information about each function is passed to the trap handler, which is used to classify faults. These are removed during the instance finalizer. Several future enhancements are planned before turning this on by default. Obviously, the additional checks will be added to MaybeHandleFault. We are also planning to add a two-level CodeObjectData table that is grouped by isolates to make cleanup easier and also reduce potential for contending on a single data structure.

[test] Deprecate and remove 'noturbofan' test variant. The variant in question was intended to test Crankshaft, which is being deprecated. Note that the variants 'nooptimization' and 'fullcode' still test configuration where TurboFan is not active.
