This adds a d8 flag --simulate-errors, which on shutdown will cause certain errors. This enables testing the reliability of sanitizers. This will cause a fatal error, a dcheck (if available) or a violation that can be detected with one of the following sanitizers: ASAN, UBSAN, MSAN, CFI. The same flag used in differential fuzzing will cause an error subsumed with the error state "fake_difference".

This specific case was not implemented or tested before. Implementing it actually simplifies some of the existing logic, since StepOut can now reuse the generic logic in debug.cc for all cases (Wasm->Wasm, Wasm->JS, JS->Wasm). Drive-by: 1) Fix typo ("skip" -> "step"). 2) Move the check for Liftoff code from debug.cc to wasm-debug.cc, where it fits better. 3) Remove a TODO which is done already.

Scopes in V8 are used to guarantee one or more properties during its lifetimes. If a scope is not named e.g MyClassScope(args) instead of MyClassScope scope(args) it will get created and automatically destroyed and therefore, being useless as a scope. This CL would produce a compiling warning when that happens to ward off this developer error. Follow-up to ccrev.com/2552415 in which it was introduced and implemented for Guard classes.

Both sample are essentially the same up to string constants since cppgc's default platform started using libplatform. The only diff between the sample is whether we call v8::V8::IntializePlatform or cppgc::InitializeProcess. Drive-by: replace CPPGC_BUILD_IN_V8 with CPPGC_IS_STANDALONE which is more descriptive.

Refactor write barriers and split calls, as e.g. DijkstraWriteBarrier also contained logic for recording slots (cards) for the young generation. The new API exposes the following: - GetWriteBarrierType(): Retrieving the type of barrier that must be emitted; - DijkstraWriteBarrier(), DijkstraWriteBarrierRange(): Dijkstra-style write barriers; - SteeleWriteBarrier(): Steele-style write barrier; - GenerationalBarrier(): Barrier for recording slots when using multiple generations; Compilers running with -O3 optimize the DijkstraWriteBarrierPolicy down to the same instructions as before the split.

With concurrent inlining, the inlining phase happens on the background thread and the data needed for the inlining phase is serialized on the main thread. The serialization phase tries to gather data about functions called which is sometimes more expensive than inlining phase itself. So it's better not to use concurrent inlining for TurboFan compilations when tiering up from Turboprop to TurboFan. Turboprop compilations don't inline and hence it is OK to continue using concurrent inlining for Turboprop compilations.

This Cl changes the priority of baseline compilation from kUserVisible to kUserBlocking. Once baseline compilation finishes, the priority is reduced to kUserVisible. The reason for using kUserBlocking is that thereby TurboFan compilation cannot block Liftoff compilation anymore. Additionally, kUserBlocking is quite appropriate, as the initial compilation does block a whole section of a web app from execution.

The logic to detect if a 'br' instruction is a branch or a return was duplicated in function-body-decoder-impl.h and in both interfaces. Apart from code duplication, this structure also made it hard to implement planned compiler improvements. This CL removes this duplication by upgrading BrOrRet (that already existed in both Liftoff and Turbofan interfaces) to an interface function and using it for unconditional branches.

This is a minor refactoring before fixing actual issues. 1) The update of the {per_isolate_data_} is moved into {FloodWithBreakpoints}, which is already taking the mutex. 2) The {PrepareStep} method takes a {WasmFrame*} directly instead of its ID. In most cases, this prevents the creation of an additional stack frame iterator.

Prototype v128.load{8,16,32,64}_lane on IA32 (stores will come later). This is pretty similar to x64 version, except that there is no signal handler for OOB access, so kProtected is not a valid access mode. Left some TODOs for myself to merge the new instruction codes (kIA32Pinsrb) with the replace lane Wasm instructions.
