[Backport] Security bug 1195331

Reland "M86-LTS: [const-tracking] Ensure map is updated before generalizing constness"

This reverts commit 4b4ad58888faf938a76e0d792c3c3a639c79e2e4.

M86 merge conflicts and resolution:
* src/objects/map-updater.cc
  Map::instance_descriptor with kRelaxedLoad dispatcher was introduced after
  8.6 branch: https://crrev.com/c/2424130. Before the patch
  Map::instance_descriptor without distpacher was used. Do the same
  here.
* test/mjsunit/regress/regress-crbug-1195331.js
  HasOwnConstDataProperty did not exist in 8.6. Add it from
  https://crrev.com/c/2566757.

Original change's description:
> Revert "M86-LTS: [const-tracking] Ensure map is updated before generalizing constness"
>
> This reverts commit 69a043b410ff83f31ceba23eab410163403c1db0.
>
> Reason for revert: causes compilation errors. kRelaxedLoad is missing.

Merged: [liftoff] Fix >=2GB memory accesses on 32-bit

We were inconsistent in handling offsets >= 2GB on 32-bit systems. The
code was still relying on this being detected as statically out of
bounds, but with the increase of {kV8MaxWasmMemoryPages} to support 4GB
memories, this is not the case any more.

This CL fixes this by again detecting such situations as statically OOB.
We do not expect to be able to allocate memories of size >2GB on such
systems. If this assumptions turns out to be wrong, we will erroneously
trap. If that happens, we will have to explicitly disallow memories of
such size on 32-bit systems.

Cherry-pick of patch originally reviewed on

Fix store handler selection for arguments objects

M108 merge issues:

      Type conflicts for the handler variable on and
      the IsWeakFixedArray() check isn't present in 108; kept

Drive-by: fix printing of handlers in --trace-feedback-updates mode.

Merged: [codegen] Install BytecodeArray last in SharedFunctionInfo

Maglev assumes that when a SharedFunctionInfo has a BytecodeArray,
then it should also have FeedbackMetadata. However, this may not
hold with concurrent compilation when the SharedFunctionInfo is
re-compiled after being flushed. Here the BytecodeArray was installed
on the SFI before the FeedbackMetadata and a concurrent thread could
observe the BytecodeArray but not the FeedbackMetadata.

Drive-by: Reset the age field before setting the BytecodeArray as
well. This ensures that the concurrent marker will not observe the
old age for the new BytecodeArray.

Manual backport of patch originally reviewed on
https://chromium-review.googlesource.com/c/v8/v8/+/5300311:
Merged: [wasm] Use correct signature index for tier-up of wasm-to-js wrapper

The wasm-to-js wrapper tierup used the canonicalized signature id lookup
for module-independent signatures to look up the canonicalized signature
id of module-specific signatures. With this CL the signature id is
looked up with the function index of imported functions and from the
dispatch table for indirect function calls instead.

Merged: [wasm] Do not inline wrappers with 'ref extern' parameter type

This was introduced in https://crrev.com/c/4212394.

The wrapper would need to test for null and throw a type error but
doesn't do that correctly.
(The test case added only tested that a null check happens either in
the wrapper or in the cast instruction because the test case was trying
to test both cases without duplicating too much which was a bad design
choice.)

For simplicity, just disallow inlining of wrappers with parameters
typed 'ref extern'. (Users should use `externref` aka 'ref null extern'
instead anyways as the non-nullability doesn't add any benefits.)
