Counters in generated code, as enabled with --native-code-counters, do not work
in the snapshot. This adds a `v8_enable_snapshot_code_counters` build option
enabled by defaut in debug mode that allows code from the snapshot to increment
the current isolate's set of counters.
For this to work, we need to add native code counters in the external reference
table.
To keep the no snapshot configuration similar, we've also enabled the
--native-code-counters flag by default for debug builds.

ever need to include inl headers again, we should split out the

V8_libbase.dll, in a component build where the dll is created,
statically links against shlwapi.dll. Shlwapi is only needed for a
single use within the debug stacktrace code and is therefore not needed
in most cases. Statically loading shlwapi also brings in user32.dll and
gdi32.dll, so this is a decent perf hit which is generally unnecessary.
This changes delayloads shlwapi so that is only loaded when actually
used.

On 64 bit Windows, the OS stack walking does not work because the V8 x64
backend doesn't emit unwinding info and also because it doesn't emit ABI
compliant stack frames. See
https://docs.google.com/document/d/1-wf50jFlii0c_Pr52lm2ZU-49m220nhYMrHDi3vXnh0/edit
for more details.
This problem can be fixed by observing that V8 frames usually all have the same
prolog and epilog:
push rbp,
mov rbp, rsp
...
pop rbp
ret N
and that it is possible to define XDATA (UNWIND_CODEs) that specify how Windows
should walk through V8 frames. Furthermore, since V8 Code objects are all
allocated in the same code-range for an Isolate, it is possible to register a
single PDATA/XDATA entry to cover stack walking for all the code generated
inside that code-range.
This PR contains changes required to enable stack walking on Win64:
EmbeddedFileWriter now adds assembler directives to the builtins
snapshot source file (embedded.cc) to emit additional entries in the .pdata and
in the .xdata section of the V8 executable. This takes care of stack walking
for embedded builtins. (The case of non-embedded builtins is not supported).
The x64 Assembler has been modified to collect the information required to emit
this unwind info for builtins.
Stack walking for jitted code is handled is Isolate.cpp, by registering
dynamically PDATA/XDATA for the whole code-range address space every time a new
Isolate is initialized, and by unregistering them when the Isolate is
destroyed.
Stack walking for WASM jitted code is handled is the same way in
wasm::NativeModule (wasm/wasm-code-manager.cpp).
It is important to note that Crashpad and Breakpad are already registering
PDATA/XDATA to manage and report unhandled exceptions (but not for embedded
builtins). Since it is not possible to register multiple PDATA entries for the
same address range, a new function is added to the V8 API:
SetUnhandledExceptionCallback() can be used by an embedder to register its own
unhandled exception handler for exceptions that arise in v8-generated code.
V8 embedders should be modified accordingly (code for this is in a separate PR
in the Chromium repository:
https://chromium-review.googlesource.com/c/chromium/src/+/1474703).
All these changes are experimental, behind:
the 'v8_win64_unwinding_info' build flag, and
the '--win64-unwinding-info' runtime flag.

This was unimplemented but is needed for Perfetto which posts delayed
tasks on worker threads e.g. drain the trace buffer into a file every x
seconds.
This is implemented by adding a second queue which holds the delayed
tasks in chronological order of 'next-to-execute'. We use an
std::multimap for the queue so that we can easily get the next delayed
task with begin().
The implementation will move delayed tasks into the main task queue
when their deadline expires.
Drive-by cleanup of the runner destructor which can just use = default.

This reverts commit f8a676707d.
Reason for revert: https://ci.chromium.org/p/v8/builders/ci/V8%20Linux%20-%20arm64%20-%20sim%20-%20MSAN/25576
I don't think I've seen MSAN being flaky. Chances are that the change to SFI's object layout indeed left some field uninitialized.
Original change's description:
> Remove builtin-function-id in SFI
>
> builtin_function_id corresponded to BuiltinFunctionId (a manually maintained list of 'interesting' functionsmainly used during optimization). With this change, we nuke builtin-function-id in favor of builtin-id and 8 bits is freed up in SFI.

Moving to gtest allows negative test cases as the current parser
implementation exits the process on a parser error. The CL adds two
small negative tests. The idea is less to get full coverage, but to
have a place for regression tests.
Drive-by-change: Lexer errors need a valid source position scope and
Json parser needs a valid SourceId, otherwise we read OOB when the
error message is generated.

This CL moves the following builtins from CSA to Torque:
TypedArray.prototype.forEach
TypedArray.prototype.reduce
TypedArray.prototype.reduceRight
A space-saving decision was made in the design -- instead of emitting
versions of the central loop for each ElementsKind, a function
pointer which knows how to read from the appropriate TypedArray
ElementsKind is constructed at the outset, and passed into the
loop. This enormously reduces codesize for the TypedArray builtins.
We'll have to see if the overhead of the builtin call affects
performance too adversely.

Design Doc: https://goo.gl/9G9d9k
The initial prototype consists of a few parts:
The VS Code extension is now built using TypeScript. The build artifact
is checked-in along side the extension. The extension now starts up
the language server when it is activated. The path to the LS
executable is configurable via VS Code settings.
The language server is a separate executable. It adds a light-weight
object model on top of a Json Parser for reading/writing LSP requests
and responses. The current server is very much bare-bones featurewise:
- Tell the client that the server can handle "goto definition"
- Recompile when Torque files change
- Goto definition support for Macros/Builtins, local variables
and arguments.

This CL introduces a new contextual 'LanguageSererData'. Its purpose
is to hold all the eagerly calculated data needed to answer
language server requests. The first thing collected are the
definitoins of some IdentifierExpresisons and macro/builtin
call-sites.
Collecting this data is not necessary for normal compilation, so it
is disabled by default and can be enabled via a Torque compiler
option. Since the holder class is a contextual for which no scope
exists during normal compilation, accidental collection of
unnecessary language server data *should* be prevented.

Template objects should be cached after they are first created and reused on
subsiquent calls to tag functions. Currently these cached objects are stored
on the feedback vector, which has appropriate lifetime, however with bytecode
flushing the feedback vector could be cleared when the bytecode is flushed,
causing the template object to be dropped.
In order to retain the cached template objects in the face of bytecode flushing,
this CL adds a weakmap for each native context that is (weakly) keyed by
shared function info, and holds a linked list of cached template objects
associated with that shared function info, indexed by feedback vector slot id.
Misses will check this weakmap, and if no entry is found, a new template object
is created and added into this weakmap alongside the feedback vector.
