During deletion in the write-back phase, we do not necessarly need
to check with HasOwnProperty before calling DeleteProperty. Since this
is observable behavior when using proxies, we remove the HasOwnProperty
check to mirror more closely what Spidermonkey does.

Host info used to be stored on the global reference underlying a Ref;
now it is stored in a JSWeakMap and hence tied to the lifetime of the
actual object on V8's heap.
Additionally, the internal metadata needed for C-API functions is now
stored on the SharedFunctionInfo and no longer overlaps with the host
info mechanism.

Rework the implementation of non-external Torque classes to use
Struct machinery rather than FixedArray machinery. This allows
Torque-only defined 'internal' classes to the automatically generate
class verifiers and printers.
As part of this change, generate C++ boilerplate accessors for
internal Torque classes, since this is a pre-requisite for the
verifiers, printers and other Struct-based functionality.
Moreover, augment the header-generating functionality in Torque
to create separate header files for field offset definitions,
internal class C++ definitions and instance types.

with 'let' when they could be bound using 'const. This test is skipped

This CL adds lint errors when 'let' bindings, arguments and labels
are not used. Note that errors for 'const' bindings will be added
later.
In cases where arguments are actually needed to match the signature,
the warning can be silenced by prefixing identifiers with "_". This
might be needed for generic specializations or builtins called from
TurboFan. Trying to use a variable or label that was marked with
"_" results in a compilation error.
Implicit arguments are not linted. They are implemented using exact
string matching. Prefixing an implicit argument with "_" in a callee
would break all callers as the names would no longer match.
Drive-by: Fix all new lint errors in the existing Torque code.

With very few exceptions, this verifies all skipped write-barriers in
CSA and Torque, showing that the MemoryOptimizer together with some
type information on the stored value are enough to avoid unsafe skipped
write-barriers.
Changes to CSA:
SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the
MemoryOptimizer by default.
Type information about the stored values (TNode<Smi>) is exploited to
safely skip write barriers for stored Smi values.
In some cases, the code is re-structured to make it easier to consume
for the MemoryOptimizer (manual branch and load elimination).
Changes to the MemoryOptimizer:
Improve the MemoryOptimizer to remove write barriers:
- When the store happens to a CSA-generated InnerAllocate, by ignoring
Bitcasts and additions.
- When the stored value is the HeapConstant of an immortal immovable root.
- When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned).
- Fast C-calls are treated as non-allocating.
- Runtime calls can be white-listed as non-allocating.
Remaining missing cases:
- C++-style iterator loops with inner pointers.
- Inner allocates that are reloaded from a field where they were just stored
(for example an elements backing store). Load elimination would fix that.
- Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole).
We could handle that in Torque.
- Double-aligned allocations, which are not lowered in the MemoryOptimizer
but in CSA.
Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this
can be handled by overload resolution (in Torque and C++).
Reland Change: Support pointer compression operands.

This brings in
third_party/inspector_protocol/encoding/encoding_test.cc
from the upstream project and makes it work for v8's
unittest suite.
encoding_test_helper.h is a V8 specific implementation,
which delegates to src/inspector/v8-string-conversions{.h,.cc},
for the utf8 / utf16 conversion routines.
I'm also fixing / updating roll.py, for future rolls.

This modifies roll.py to update namespaces and header guards.

third_party/encoding/encoding{.h,cc} are already up to date,

Keep the existing method for compatibility, by converting
to json from CBOR using the inspector_protocol_encoding library,
via a v8 specific interface library that directs routines for
converting between strings and doubles to v8's implementations.
This change also brings in the encoding.h / encoding.cc files from the

With very few exceptions, this verifies all skipped write-barriers in
CSA and Torque, showing that the MemoryOptimizer together with some
type information on the stored value are enough to avoid unsafe skipped
write-barriers.
Changes to CSA:
SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the
MemoryOptimizer by default.
Type information about the stored values (TNode<Smi>) is exploited to
safely skip write barriers for stored Smi values.
In some cases, the code is re-structured to make it easier to consume
for the MemoryOptimizer (manual branch and load elimination).
Changes to the MemoryOptimizer:
Improve the MemoryOptimizer to remove write barriers:
- When the store happens to a CSA-generated InnerAllocate, by ignoring
Bitcasts and additions.
- When the stored value is the HeapConstant of an immortal immovable root.
- When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned).
- Fast C-calls are treated as non-allocating.
- Runtime calls can be white-listed as non-allocating.
Remaining missing cases:
- C++-style iterator loops with inner pointers.
- Inner allocates that are reloaded from a field where they were just stored
(for example an elements backing store). Load elimination would fix that.
- Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole).
We could handle that in Torque.
- Double-aligned allocations, which are not lowered in the MemoryOptimizer
but in CSA.
Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this
can be handled by overload resolution (in Torque and C++).

This changes the syntax for constructing structs and classes to explicitly
mention the fieldnames, similar to JavaScript object literals.
The fields still have to be listed in the same order as in the struct/class
declaration.
As in Javascript, {foo: foo} can be abbreviated as {foo}.
Example:
macro NewJSArray(implicit context: Context)(
map: Map, elements: FixedArrayBase): JSArray {
return new JSArray{
map,
properties_or_hash: kEmptyFixedArray,
elements,
length: elements.length
};
}
Drive-by cleanup: Make struct and class constructors follow the same pattern
in the parser and the AST.

This CL changes Array#sort to work roughly like:
1) Call [[Get]] on the receiver in [0, length) and store to FA
2) Use the existing TimSort to sort that FA
3) Call [[Set]] on the receiver in [0, length) using the result
This has the advantage that we no longer need different fast-paths
for the sorting algorithm itself, only for step 1 and 3. This results
in a code size reduction of ~2650 bytes.
This CL does not include optimizations that elides step 1 or 3.

Intrinsic changes:

- Add %RawPointerCast, which is similar to %RawObjectCast but must be
used for all subtypes of RawPtr.
- Add %RawConstexprCast, which allows one constexpr to be be cast to
another at compile time. It translate to an appropriate static_cast
in the generated code
- Add %FromConstexpr, which handles most of the standard cases of
generating XXXConstant CSA nodes from constexpr constants. It uses
either SmiConstant, NumberConstant, StringConstant, IntPtrConstant
or Int32Constant, depending on the cast-to type generic <To> type.
- Add support for intrinsics that return constexpr results.
Cleanup:
- Turn FromConstexpr into a generic with two generic types, a <To> and
a <From> type. Most FromConstexpr can use the new %FromConstexpr
intrinsic rather than provide an explicit implementation.

The array length is modifiable by user code that is called as a
side-effect during the sorting algorithm. We thus cannot base any
guarantees on the current length, but must reference the initially-read
array length instead.
Note that even though the algorithm may read and write from beyond
the current array length value, this adheres to the spec, which only
requires accesses to be within the original array dimensions (i.e.: 0
<= i < original array length).
