Instead of de-sugaring destructuring assignment in the parser (using the
pattern rewriter), pass the Object/ArrayLiterals through to the bytecode
generator, which can desugar them in-place.
This allows us to decrease the amount of AST node creation, and improve
the generated bytecode using domain-specific knowledge. As a side effect
we partially fix an old execution ordering spec bug.
Currently only implemented for assignments, not declarations, as the
latter has some additional complexity.

This is purely a renaming change. The ES spec uses the term 'detach'
for the process of removing the backing store of a typed array, while
V8 uses the historical term 'neuter'. Update our internal implementation,
including method names and flag names, to match the spec.
Note that some error messages still use the term 'neuter' since error
messages are asserted by some embedder tests, like layout tests.

Previously we only supported strings and not filenames. This
changes the default to filename and adds a new `type: string` which can
be passed `options` to allow for strings to be passed in test code.

This CL implements a generic baseline version of Array.p.unshift
in Torque, enabling us to remove the JS fall-back.
The elements-accessor fast-path is still used, but the check whether
to use it is also moved to Torque.
Support for sparse JSArrays is removed.
Drive-by change: Small refactoring in builtins-array that will
get extended to other array builtins in a follow-up CL.

Before, splice was implemented with a C++ fast path and a
comprehensive JavaScript version.
This impl. is entirely in Torque with a fastpath for SMI,
DOUBLE and OBJECT arrays, and a comprehensive slow path.
The same level of "sparse" array support as given by the
array.js implementation is included.
This reland addresses several issues:
* Removed "sparse" array support from splice.
* Addressed ClusterFuzz issue 876443:
The test and code that uses the fix is in this CL.
The fix in isolation can be seen here:

The spec specifies that search and standard can not be valid values
for the collation extension keyword. Instead users are expected to use
the options bag to set the correct usage options.
But, ICU expects the usage option to be set through the collation
extension value.
In this patch, we set the usage option using the collation extension
value in ICU. For resolvedOptions, we filter out this extension value
using ICU to be spec compatible.
Previously, we stored the usage option on the JSCollator instance. But
this patch changes the logic to just look it up from the icu::Collator
when required. This saves one word of memory.
This fails a test262 that was incorrectly fixed. A follow on patch
will fix the test262 test.

This patch ports most of the Intl.Collator from JS to C++.
The Intl.Collator object no longer stores all the resolved
values. Instead these are looked up on demand as part of
Intl.Collator.prototype.resolvedOptions(), saving several words. In
the future, we can cache the result of the resolvedOptions as well.
In this patch, we use ICU to do parsing of the unicode extension in
the bcp47 language tag instead of using a custom extension parser.
This patch also fixes several spec compliance bugs as well.

1. Check for grandfathered tags without preferred value upfront

2. Lowercase the input before structural validity check to simplify
check for grandfathered tag without preferred value as well

intl/general/grandfathered_tags_without_preferred_value is added and
intl/general/language_tags_with_preferred_values is changed to check

When storing an indexed property in a typed array, it's necessary to
convert the value to a Number (or to a Bigint) before performing the
bounds check, per
https://tc39.github.io/ecma262/#sec-integerindexedelementset.
This CL adds appropriate type conversions in
Object::SetPropertyInternal (which technically is reached after the
bounds check has already occurred, but this isn't observable yet ---
In the future, once OOB accesses on TypedArrays actually throw, this
will need to be refactored again), and in StoreFastElementStub, and
ElementsTransitionAndStoreStub (via CSA::EmitElementStore).
The change was not necessary in TurboFan, as
JSNativeContextSpecialization already performs the value conversion
before the boundscheck.
The result is some fixed test262 tests, and some new test coverage
for this behaviour in mjsunit.
