Behavior in Release mode was correct; Debug mode triggered a DCHECK
failure that indicated an inefficiency: when a requested truncation
would be a no-op, we should return the original BigInt, rather than
creating a copy. In the special case of -2^(n-1), i.e. the smallest
negative n-bit integer, getting truncated to n bits, with n being a
multiple of kDigitBits, this shortcut was not taken.

Since we use a ScopedPtrList to track cover grammar expressions we don't know
the position of the commas anymore. The position of the commas was used to
demark the initializer, which is needed to figure out whether we need hole
checks for variable references. (Typically only references within the
initializer need hole checks for the initialized variable.) Since we didn't
have the comma position, we simply used the position of the first expression as
the position of any subsequent comma, which would make it seem as if the
initializer body wasn't in the initializer. Now instead we simply use the
position of the subsequent parameter as the end of the initializer, which is
close enough.

The Ignition statement list visitor will skip the rest of the
statements in the list if it hits a jump statement (like a return
or break), as the rest of the code in the list can be considered
dead.
return;
dead_call(); // skipped
However, since this is at an AST node level, it does not take into
account condition shortcutting:
if(2.2) return;
dead_call(); // not skipped
There is also a second dead code elimination in Ignition compilation, at
the bytecode array writer level, where a bytecodes are not emitted if an
"exit" bytecode (Return, Jump, or a few others) has been written, until
the next basic block starts (i.e. a Bind).
This can cause an issue with statements that resurrect the bytecode
array writer part-way through their visit. An example is try-catch
statements, which save the context to a register, and then Bind to start
the try region.
For the case:
if (2.2) return;
try { // try statement not skipped
...
}
the bytecode writer is called with
OutputReturn() // exit bytecode seen
OutputMove(<context>, r1) // not emitted
Bind(&try_begin) // starts new basic block
// try body
So, the try is emitted, but without saving the context to a register.
This means that the liveness analysis sees the read of that register
(as the output liveness of throwing bytecodes), but does not have a
write to the register, which means that the liveness escapes.
This patch fixes this by using the bytecode array writer dead-code
elimination (i.e. "exit bytecode seen") to inform the statement list
visitor, so that in this example the try statement is not visited at
all.

Previously, we finalize all compile jobs at once. This keeps the zone memory
in every compile job alive until the end. This contributes to a high peak
memory when many functions are compiled eagerly, for example when producing
cache data for the ServiceWorker cache.
Memory tracked by the AccountingAllocator in bytes, prior to this change in
the test case:
peak memory after init: 8192
peak memory after lazy compile: 41200
peak memory after lazy compile: 41200
peak memory after eager compile: 164256
With this change, if we are compiling on the main thread, we finalize every
compile job as soon as it is done and dispose the compile job and its zone
memory.
After this change:
peak memory after init: 8192
peak memory after lazy compile: 41200

Compilation units currently contain pointers into allocated space that
contains the code of the respective function. This requires us to keep
the StreamingDecoder alive as long as compilation is still running
(including tiering).
This CL refactors this by having an additional redirection
(WireBytesStorage) which can point to either the StreamingDecoder or
the NativeModule. We only keep the code section buffer alive as long as
the StreamingWireBytesStorage is still in use.
I will further refactor memory ownership in a follow-up CL to not make
the AsyncCompileJob keep the StreamingDecoder alive.

returning the original value.
Also modifies the signature of "CopyPropertyArrayValues" to take a
"DestroySource" enum, indicating whether or not the resulting object is
supplanting the source object or not, and removes all default
parameters from that macro (which were not used anyways).
This corrects the issue reported in chromium:901301, where
StaNamedOwnProperty was replacing the value of a MutableHeapNumber

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

These tests are also used for streaming. This CL changes the test to
actually output the exception that unexpectedly happened.

Any sane platform would process foreground tasks in a FIFO order. Hence
our mock platform in the tests should do the same.

in TurboFan, CSA, Wasm and compiler tests. Tagged values decompression
logic will depend on the machine type of the value being loaded so it must
be correct.

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).

- Fix ParseBCP47 to return just the extension. The second argument to
substr function is actually the length, not the end position of the
substring :')
- Remove extension keys that aren't part of the relevant extension keys
- Use 'ca' as an relevant extension key for DateTimeFormat
- Use the canonicalized locale tag after create the ICU locale is
created, rather than the input locale tag.

This is to ensure the snapshot is deterministic.
Internal fields can contain:
- reference to heap object
- embedder-defined aligned pointer
- a smi
The latter two are not distinguishable by V8, so if the serializer
callback returns non-zero value, we consider it to be an aligned pointer
and clear it to ensure that the snapshot does not contain memory
addresses that may not be deterministic. If the callback returns
{ nullptr, 0 } as result, we consider it to be a smi or some in-place
data that we then serialize verbatim.
