This explicitly passes along the break reason when requesting a pause
that is handled via an interrupt. Pushing the break reason is not
enough (as done before), as the reason may be used and consumed on
another pause call that triggers a setPauseOnNextCall.

This is the 2. CL in a series of CollectGarbage refactoring CLs.

It moves two kinds of callbacks to the epilogue of CollectGarbage:
- Weak second pass phantom callbacks
- GCEpilogueCallbacks

As the prologue callbacks have also been moved outside the GC cycle,
with this CL the need for nesting tracers is eliminated. DCHECKs are
put in place to ensure this.

The 32-bit value is zero-extended to pointer size, which is a no-op on
32-bit systems. The operation changes nothing about the signedness of
the value, so the old name was a bit misleading.

We also provide one unified no-op implementation for all 32-bit systems.

If PKU is used, we just called {pkey_mprotect} and called it a day,
whereas {PageAllocator::SetPermissions} also discards the system pages
when switching to {kNoAccess} (both in {OS::SetPermissions}, which is
used by the default platform, as well as the GIN platform used in
Chrome).

In order to avoid memory regressions when using PKU, this CL changes the
PKU implementation to behave like the POSIX {OS::SetPermissions}
function and also discard system pages when removing all access.

Previously we'd predict exceptions thrown in [[Reject]] handlers as
always caught (by PromiseRejectReactionJob), but that's not what is
actually specified in ECMAScript. The PromiseRejectReactionJob will turn
any exception thrown into a promise rejection just like we do in the
case of PromiseFulfillReactionJob, and so the catch prediction should
match that behavior.

Those versions are broken, and sporadically reset the PKRU register on
context switches (observed on ChromeOS only). This was fixed by this
patch:
https://lore.kernel.org/all/20210623121456.399107624@linutronix.de/

Thus we detect the running kernel version (once per process), and
disable PKU if we detect a potentially broken kernel version.

the others.

Runtime_HasProperty already does the right thing; this CL is directing
more cases to it.

We can now specify the trials for clusterfuzz using the file
clusterfuzz_trials_config.json. There is also a presubmit check
to make sure that it is formatted correctly.

This reverts commit 517ed4ad.

Reason for revert: There still seems to be an issue on V8 Win msvc related to this CL (https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Win64%20-%20msvc/20568/overview).

Original change's description:
> Reland "[Torque] Generalize Torque literals to larger size"
>
> Previously, literals in Torque were stored as double values, which
> made it impossible to precisely represent 64 bit integer values.
> This CL replaces the old literal expression with an integer and
> floating point literal expression that are unbounded in size. We
> allow implicit conversion of these literals to arbitary integer
> and floating point types respectively and insert a corresponding
> bounds check into generated CSA.
>
> Changes in the reland: Simplified IntegerLiteral to single digit.
