To avoid shrinking the unregister token map on each pop of the cleared
cell list, the Torque implementation of the cleanup loop avoids
shrinking the map until the end of the loop.
To support that, PopClearedCellHoldings is refactored to the Torque
PopClearedCell which calls the
JSFinalization::RemoveCellFromUnregisterTokenMap and the runtime
ShrinkFinalizationRegistryUnregisterTokenMap. The former cannot GC is
and is implemented in CSA as a fast C call. The latter can GC and is a
runtime call.
This also incidentally makes uses of FinalizationRegistry without
unregister token a fast path that doesn't have to leave Torque.

The source position is set to the function call (console.log) not the
spread (..x), in the bytecode generator, as the spread operation is
done as part of the CallWithSpread bytecode.
The CallPrinter stops at the function call and doesn't look at the
arguments as well (in CallPrinter::VisitCall) to see if the error is
from an incorrect spread operation.
With this patch, we pass some state to the CallPrinter in the
CallWithSpread error case and check that in CallPrinter::VisitCall
before returning.
For the given source string:
```
x = undefined;
console.log(1, ...x);
```
Previously, the error was -
```
test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
console.log(1, ...x);
^
TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))

Add kWasmS128 to the list of supported types, and implement Fill for all
the architectures so that LocalGet works.
Add a new test file to contain tests that run only on Liftoff, and
assert that the code is indeed compiled by Liftoff.
We cannot rely on the nooptimization variant for testing
because by default, if Liftoff compilation fails, it will fall back to
Turbofan, and we accidentally get a test passing.
We skip these tests on mips architecture that don't support SIMD, since
there is no way to implement these, and we don't have a "lowering" phase
for Liftoff.
As we implement more of SIMD in Liftoff, we can add more
tests to this file and ensure correctness. Future patches will introduce
support for globals and params.

Currently there are two ways wasm locations are represented in the
inspector. This remains unchanged for now. Also, currently there are
multiple ways location is represented within V8, with the line number
sometimes being a function index and sometimes being 0, and the column
number being a byte offset which is sometimes function relative and
sometimes module relative. With this change, the line number is never
used within V8 (it is always 0), and the column number is always a
byte offset from the beginning of the module. This simplifies
translation logic and keeps it in one place, and will simplify future
changes to wasm location representation in the inspector API.

d8 treats files with the .mjs extension as modules instead of
classic scripts. Thus, the `// MODULE` pragma and its corresponding
logic in test runners can be removed in favor of explicitly adding
the extension.

Perform a best-effort check for module context and provide an
appropriate error.
As seen from the import-blah-script.js test, we could have invalid
import expressions in a script context that could result in an error
saying "Cannot use import statement outside a module" which isn't
the ideal error because the error is an incorrect import
expression.
But, when the developer changes to a module context, the
correct error is thrown.
To fix this, we'd have to refactor and call ParseImportDeclaration,
and then throw an appropriate error, which seems like a lot of
overhead for not enough gain.

This patch implements the access of private methods:
- When building property loads, check whether it requires
a brand check. If so, build the brand check and load the
property (the method) from the context instead.
- Throw type errors when there is an attempted write to private
methods.

Currently, in wasm-function stack traces, v8 displays the decimal offset
from the start of the function. However, the WebAssembly WebAPI
specification says that it should be a hex offset into the module.
This change makes the stack trace display with hex module offsets, as
well as fixing all the unit tests that depended on the old behaviour.

This is a reland of 3dd5661204
The reland introduces a new flag "--experimental-stack-trace-frames".
The flag is disabled by default, but enabled for relevant tests.
The flag stays disabled by default until API frames are eagerly
symbolized to prevent leaks in blink web tests.

This fixes the source position printed in the stack trace for exceptions
rethrown from within Wasm code. This only affects the message propagated
to the console, not the trace stored as part of the exception object.
Note that there still is a more fundamental issues with preserving the
original message of a caught exception and funneling it through to each
rethrow site, which is still missing. This change just makes sure that

I thought about potentially adding the identifer ref to the error but
that would require allocating a new string or at the very least
increasing the size of the resulting cons string. Given that the
parser is pretty performance sensitive, I've decided to not display
the identifier.
Previously, the error was:
_test.js:3: Error
a[foo].c = () => { throw Error(); };
^
Error
at a.(anonymous function).c (_test.js:3:26)
at _test.js:5:1
With this patch, the error becomes:

As a side-effect, we also have to check if a variable is unused in the

skip generating code/SFIs for dead variables/functions.

We only figure out that variables are non-simple parameters once we see the

Storing a VariableProxy in declarations means that a declaration and
initialisation assignment are tightly coupled to use the same var. In
particular, this means that Var declarations in with scopes have to
clone the VariableProxy to split the declaration and initializer LHS
lookup.
This patch changes declarations to point directly to the Variable, not
the VariableProxy. This will allow future refactoring to decouple
declarations and initialisations.

For desrtucturing assignments from null/undefined, we throw an error
that references the destructuring object literal's property name, e.g.
for
var { x } = null;
we report that we cannot destructure 'x' from null.
Rather than calculating this property during bytecode generation (and
including it in the bytecode as an argument to the type error
constructor), we can calculate it at exception throwing time, by
re-parsing the source in a similar way to the existing call site
rendering.
This slightly decreases bytecode size and slightly decreases the amount
of work the bytecode compiler needs to do. In the future, it could also
allow us to give more detailed error messages, as we now have access to
the entire AST and are on the slow path anyway.

Emit a single destructuring assignment for destructuring declarations,
which can be desugared by the bytecode generator. This allows us to
remove destructuring desugaring from the parser (specifically, the
pattern rewriter) entirely.
The pattern "rewriter" is now only responsible for walking the
destructuring pattern to declare variables, mark them assigned, and
potentially rewrite scopes for the edge case of parameters with a sloppy
eval.
Note that since the rewriter is no longer rewriting, we have to flip the
VariableProxy copying logic for var re-lookup, so that we now pass the
new VariableProxy to the variable declaration and leave the original
unresolved (rather than passing the original through and rewriting to a
new unresolved VariableProxy).
This change does have some effect on breakpoint locations, due to some
of the available information changing between the parser and bytecode
generator, however the new locations appear to be more consistent
between assignments and declarations.

Since it's explicit what we're tracking, we can immediately throw errors in
certain cases, and ignore irrelevant errors. We don't need to use the
classifier itself to track "let let", since we know whether we're parsing a
"let". Errors that were previously (almost) always accumulated are now
immediately pushed to the scopes that care (parameter initialization errors).
This CL drops avoiding allocation of classified errors, at least for now, but
that doesn't affect performance anymore since we don't aggressively blacklist
anymore. Classified errors are even less likely with the more precise approach.
ParseAssignmentExpression doesn't introduce its own scope immediately, but
reuses the outer scope.
Rather than using full ExpressionClassifiers + Accumulate to separate
expressions/patterns from each other while keeping track of the overall error
state, this now uses an explicit AccumulationScope.
When we parse (async) arrow functions we introduce new scopes
that track that they may be (async) arrow functions.
We track StrictModeFormal parameters in 2 different ways if it isn't
immediately certain that it is a strict-mode formal error: Either directly on
the (Pre)ParserFormalParameters, or on the NextArrowFunctionInfo in the case
we're not yet certain that we'll have an arrow function. In the latter case we
don't have a FormalParameter object yet, and we'll copy it over once we know
we're parsing an arrow function. The latter works because it's not allowed to
change strictness of a function with non-simple parameters.

This changes the split from AssignmentPattern and BindingPattern to Pattern and
BindingPattern. Pattern collects all errors that are invalid in both assignment
and binding pattern contexts. Binding pattern additionally collects errors for
binding pattern contexts (property access isn't a valid target). The
distinction is piggybacked on to distinguish assignment vs binding pattern
errors since binding pattern verification will first throw the binding pattern
error.
Since we don't throw pattern error as binding pattern as well, this can mean
that a later binding pattern syntax error will show up before an early pattern
error. Since that just changes the message to another syntax violation, I think
that's fine.

Rename variables and flag names so that the classes can be reused
by private methods implementation.
In particular:
Rename "fields" to "members" in the initializer so that we can
initialize both fields and private methods/accessors there,
for example:
instance_fields_initializer -> instance_members_initializer
InitializeClassFieldsStatement -> InitializeClassMembersStatement
Rename "private field" to "private name" for the private symbols
used to implement private fields so that we can use them to
store private methods/accessors later as well, for example:
private_field_name_var -> private_name_var
NewPrivateFieldSymbol -> NewPrivateNameSymbol

This is a reland of 1c48d52bb1.
It turned out that IterableToList doesn't always behave according to
the ES operation with the same name. Specifically, it allows holey arrays
to take its fast path, which produces an output array with holes where
actually "undefined" elements should appear.
This CL changes the version of IterableToList that is used for spreads
(IterableToListWithSymbolLookup) such that holey arrays take the slow path.
It also includes tests for such situations.

assertPromiseResult, adds better stack traces, and adds tests for all
the important cases I can think of.
