We used to update profiler ticks after tiering up decisions when tiering up from Ignition and update the ticks before when tiering up from mid-tier optimized code. This meant we added special cases to account for this difference. This cl makes updating the ticks uniform by always updating the ticks before tiering up decisions. Also adjusts the heuristics to take this into account.

cppgc_unittests uses tracing (e.g. when setting the TracingController in tests.h) and thus needs to depend on v8_tracing. It cannot inherit the dependency since the cppgc_unittests_sources v8_source_set doesn't depend on cppgc.

The error simulation works and crashes during the smoke test are detected. But now this masks real crashes (https://crbug.com/1153200), therefore this change subsumes smoke-test crashes with --simulate-errors under a separate crash state. Now Clusterfuzz will detect the case "unexpected crash" as fixed, but create a new bug for "simulated crash". Which we will keep open forever.

Avoid virtual call on the fast path when invoking Heap::MonotonicallyIncreasingTimeInMs by using base::TimeTicks directly. With --predictable we need to fall back to Heap::MonotonicallyIncreasingTimeInMs though. Convert base::TimeTicks to milliseconds as double, since this was the format GCTracer was using internally.

1. Don't optimize small functions early when tiering up from ignition to Turboprop. 2. When tiering up from Turboprop to Turbofan scale the ticks so we optimize small functions at roughly same time as default. 3. Adjust for the fact that profiler ticks are updated before performing the ShouldOptimize check when tiering up from TP -> TF.

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.
