Previously, when accessing SandboxedPointer fields with the sandbox
disabled, we would always do a ReadUnalignedValue/WriteUnalignedValue.
However, that is only necessary when pointer compression is enabled.
Otherwise, the field will be properly aligned.

This CL also factors out the logic to determine when to use an unaligned
or aligned read/write for a field into two new helper functions.

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.

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.
