This prepares using ochang_js_fuzzer with foozzie. The fuzzer uses tests from CrashTests in the corpus. This leads to a loop when used with differential fuzzing, as foozzie dedupes failures based on the original file path. Foozzie finds a new failure for the existing failure in CrashTests, for which clusterfuzz creates a new crash test and so on. This subsumes all failures from CrashTests under the same key. Once such a failure is reported, a developer can add it to a mapping in foozzie.py, after which the global key can be used again by clusterfuzz to report another failure.

Allocating a new feedback vector happens in two steps: We create an empty structure and then initialize the array based on the FeedbackMetadata.When allocating a new feedback array we could trigger a GC which might flush the bytecode and associated feedback metadata. This shouldn't happen in normal cases, because we either allocate feedback vector after compilation or when we reach the expected budget. In both cases, the age of the feedback vector should be 0 and hence bytecode shouldn't be flushed. However, with debugger enabled we may allocate feedback vectors even when the bytecode array is old for example: when we enable precise invocation counters. This also causes issues in tests with --stress-flush-bytecode. In the stress mode we flush bytecode without considering the age. Holding on to the feedback metadata prevents crashes in such cases.

Instead of keeping a single {stepping_frame_} per native module, we now keep one frame id per isolate. Hence, each isolate can step through a different frame, independent of other isolates. The on-stack-replacement of the stepping frame already works on a per-isolate basis, since we only replace the return address of a single frame, part of the isolate that requested stepping. The new test (which also executes in a variant with two concurrent isolates) revealed some more data races to fix.

Make sure that any GCs required for off-thread heap merging happen before any off-thread handle transferring (both transferring using OffThreadTransferHandle, and the handles created for the string slot fixups). This is to avoid the marker from walking Handle roots that point into off-thread pages which the sweeper doesn't see (and can't clear mark bits on) Now, the merging and handle creation is atomic as far as the GC is concerned. The merging is done before handle creation to avoid the incremental marker from entering off-thread pages, but we ensure that the raw objects pointers that point into the off-thread pages (which are used for creating the main-thread handles) stay valid until the handle creation completes. Since handle transfer now happens in the middle of publishing, this patch also moves the OffThreadTransferHandleStorage ownership over to OffThreadHeap. This requires some header juggling to avoid leaking OffThreadTransferHandleStorage into the off-thread-isolate header.

This is a reland of 6204768b The original issue exposed the problem that NumberEqual performs implicit conversion of oddballs to numbers, which is incorrect for abstract equality comparison (i.e. 0 == null must not be true). This reland fixes this by applying the following steps: * Introduced a new kNumberOrBoolean value for CompareOperationFeedback, CompareOperationHint, TypeCheckKind and CheckedTaggedInputMode. * In CodeStubAssembler::Equal: Further distinguish between boolean and non-boolean oddballs and set feedback accoringly. * In JSTypedLowering: Construct [Speculative]NumberEqual operator with CompareOperationHint::kNumberOrBoolean, when this feedback is present. JSOperatorBuilder and operator cache are extended accordingly. * In SimplifiedLowering: Propagate a UseInfo with new TypeCheckKind::kNumberOrBoolean. * This leads to the generation of CheckedTaggedToFloat64 in RepresentationChanger with new CheckedTaggedInputMode::kNumberOrBoolean. * In EffectControlLinearizer: Handle this new mode. Accept and convert number and boolean and deopt for rest. Original change's description: > [turbofan] Improve equality on NumberOrOddball > > This CL cleans up CompareOperationFeedback by replacing it with a > composable set of flags. The interpreter is changed to collect > more specific feedback for abstract equality, especially if oddballs > are involved. > > TurboFan is changed to construct SpeculativeNumberEqual operator > instead of the generic JSEqual in many more cases.

Embarrassingly, while integrating VerifyRegExpSyntax into SpiderMonkey, I realized that I had refactored away the RegExpCompileData* argument, which is necessary for emitting error messages when parsing fails.

The interpreter is missing a static cast when extracting lanes smaller than int32_t and doing an unsigned extend. The array in Simd128 is signed, so a direct cast to uint32_t will be a signed extension. The fix is to, in the unsigned case, cast to unsigned (of the appropriate size) first, then cast to uint32_t.
