729d5de6a2 [api] Define TypedArray::kMaxLength in api.cc
Otherwise the value cannot be used in gtests in EXPECT_GT expressions.
The reason is that EXPECT_GT takes values by reference and not by
value, so the declaration in v8.h is not enough.

dbbdd0eca2 Reland x3 "[runtime] Remove extension slots from context objects"
Original change's description:
> [runtime] Remove extension slots from context objects
>
> Context objects have an extension slot, which contains further
> additional data that depends on the type of the context.
>
> This CL removes the extension slot from contexts that don't need
> them, hence reducing memory.
>
> The following contexts will still have an extension slot: native,
> module, await, block and with contexts. See objects/contexts.h for
> what the slot is used for.
> The following contexts will not have an extension slot anymore (they
> were not used before): script, catch and builtin contexts.
> Eval and function contexts only have the extension slot if they
> contain a sloppy eval.
>

891f5dd4cd [regexp] Force RegExpResult to slow lookup hidden internal fields.
Currently, RegExpResult builds match indices lazily using data stored
in hidden internal fields on the result object itself. Unfortunately,
if an internal field is deleted, it can cause these hidden fields
to migrate to a dictionary, making indexed lookup unsafe. This CL
forces slow but safe lookup for these fields when lazily building
indices.

31e08912bb [regexp] Add a histogram counter for # of backtracks
The new regexp_backtracks / V8.RegExpBacktracks counter tracks the
number of backtracks performed per regexp execution. The results can
help us prioritize related work.

Note that we only count backtracks in the interpreter. Jitted code is
ignored. With our current regexp tiering strategy, that means we count
backtracks only in the first execution of each regexp.

e79d34ee36 [heap] Slots are either in sweeping or old-to-new RS after Full GC
This CL ensures that recorded slots are either in the sweeping or the
old-to-new remembered set after mark-compact depending on whether the
page was already swept or not.

All pages that are swept during the evacuation phase also have their
remembered sets merged. is_local() is renamed to
is_compaction_space() and non-virtual. The PagedSpace now not only
knows whether it is a compaction space or not but also for which
collection through the compaction_space_kind_ field. This allows
RefillFreeList to merge the remembered sets immediately also for the
mark-compact collection.

7ff8299231 [parser] Push variables of non-arrow parenthesized expression to parent
Parenthesized variable names are valid references for assignment. To make sure
we can properly mark the variable as assigned, we should push parenthesized
variables to the outer expression scope after the parenthesized expression is
guaranteed to not be an arrow head; so that the variable list of the parent is
complete.

Technically we could probably get by with simply pushing a single variable,
since more complex expressions aren't valid parenthesized assignment targets:
(a) = ... and [(a),(b)] = ... are valid, but ([a,b]) = ... isn't.
It doesn't really seem worth it though.

a5a0eb8bf3 [base] Check ThreadedList integrity after Add
If the same VariableProxy is added to a ThreadedList twice, it will
introduce a cycle which would cause a DCHECK failure on the next Add.
This makes it DCHECK as soon as an element is added that already has a
"next" value set.

419b4e7ea5 [torque] replace name mangling with unique numbering
Name mangling is hard to get right and not easy to read.
This CL replaces the remaining name mangling of types and generics
with simpler names that are not always unique, but then fixes them
up by appending a unique counter.

For struct types, this required an @export annotation since we use some
struct types in CSA.

Drive-by-fixes:

- Overwrite the copy constructor of Type to clear the list
of alias names when creating a new type.

- Change the existing append-a-number scheme to have different
  counters for each name. This the number of changed names when adding
  something and is more readable.

c4f502ed4d Remove JS natives support, step 3
The natives blob was deprecated in V8 7.8. This CL removes all related
functionality, including:

- Build system support, i.e.: generation of natives_blob.bin and the
v8_extra_library_files gn flag.
- Related scripts (js2c.py, concatenate-files.py).
- Related API functions (SetNativesDataBlob,
InitializeExternalStartupData).
- Natives bootstrapping logic.
- The InternalArray type (previously exposed through natives).
- Other natives-exposed builtins.
- Inlining of these builtins.
- The dedicated 'uncached external one byte string' type.

Step 1 landed in https://crrev.com/c/1824944.
Step 2 landed in https://crrev.com/c/1835536.
Step 3 (this CL) removes these all functionality related to natives
support in V8.

777fa98cc4 Make SetSyntheticModuleExport throw instead of crash for nonexistent export name
Per spec, Module::SetSyntheticModuleExport should throw a ReferenceError
when called with an export name that was not supplied when constructing
that SyntheticModule.  Instead, the current implementation crashes with
a failed CHECK().

Add a new Module::SyntheticModuleSetExport that throws (without an ensuing
crash) for this case, and deprecate the old
Module::SetSyntheticModuleExport.

cdf8925e1a Fix JSEntry unwinding data on Windows ARM64
The current unwinding data for JSEntry correctly restores the frame
pointer and program counter from the caller frame, which might or might
not be sufficient to continue unwinding, depending on the contents of
that caller frame. Currently, the cctest StackUnwindingWin64 is broken
(at least with my build config) because the caller frame also needs the
stack pointer, which is not restored correctly.

In particular, I see this xdata for v8::internal::GeneratedCode<...>,
which is the function that calls Builtins_JSEntry:

10400015 : 2 code words, 1 epilog, function length=15
01000012 : epilog starts at 12 and its unwind handler starts at 4
e405c8d2 : save_reg x=b z=8
           alloc_s x=5
           end
e405c8d2 : same thing but for the epilog

The prolog that corresponds to the unwind codes above is:

sub sp, sp, #50
str lr, [sp, #0x40]

This change emits slightly more complicated unwinding data for JSEntry
so that the frame pointer, stack pointer, and program counter can all be
restored.
