FLAG_disable_write_barriers is a constexpr so the V8_LIKELY macro isn't
necessary. Interestingly, it can also cause clang to warn that the code
is unreachable, whereas without `__builtin_expect()` the compiler
doesn't mind. See for example:

```
constexpr bool kNo = false;

void warns() {
  if (__builtin_expect(kNo, 0)) {
    int a = 42;
  }
}

void does_not_warn() {
  if (kNo) {
    int a = 42;
  }
}
```

Compiling V8 for arm64 with both `v8_disable_write_barriers = true` and
`v8_enable_pointer_compression = false` would trigger this warning.

This CL reverses the count logic for the tiering strategy of the
js-to-wasm wrappers. The initial approach was that calls to each
function were counted up, until a threshold was reached and the function
would tier up. With this CL, each function is assigned a budget of calls
that can be handled through the generic wrapper. Calls are counted down
until the budget is exhausted, which will trigger the tier-up
for the function.

This approach comes with two advantages. Firstly, determining whether
a function's budget is exhausted is as simple as checking the flags set
from the decrement of the budget. Secondly, the code generated by the
generic wrapper does not depend on the specific value of the initial
budget.

The fuzzer is expected to generate a lot of syntax and runtime errors,
and the respective messages just flood the fuzzer output. By always
putting a {TryCatch} scope around the execution, we prevent those
messages from being printed.
At the same time, inspector tests need to properly propagate uncaught
exceptions in the backend to the inspector, and fail on uncaught
exceptions in the frontend.

This CL allows for all these behaviours by extending the
{CatchExceptions} enum and the {TryCatch} logic in the task runner.

Drive-by: Use {base::OS::ExitProcess} instead of the explicit
{fflush} and {_exit}.

Turboprop should tierup to OSR roughly at the same time as TurboFan,
so we wait for kProfilerTicksForTurboPropOSR ticks before OSRing. This
value was incorrect because we OSR after 4 ticks (we increment the ticks
after the tiering up decision). Also, we wait for additional ticks based
on function size. That should also adjust for the lower interrupt budget

This CL lets Torque generate the Context C++ class and BodyDescriptor
for Context.
This requires two Torque changes:

- Allow @generateBodyDescriptor on @abstract classes, since all Context
  classes share the same BodyDescriptor.

- Add a new annotation @relaxedWrite, which makes C++ setters
  use WRITE_RELAXED_FIELD instead of WRITE_FIELD.
  Attention: As a side-effect, this CL disables using
    WRITE_RELAXED_FIELD by default for all non-array fields. If this
    causes problems, we should manually add @relaxedWrite to the
    corresponding fields.

This adds support for OrderedHashSet, OrderedHashMap, and
OrderedNameDictionary to Object::Print.
It also refactors the existing printing of (unordered) hash sets, maps,
and dictionaries to increase code reuse.

around cppgc types.

return types depending upon whether the architecture is 64-bit or 32-bit.
