This CL aims to address the regressions that we saw in Octane 2.1,
particularly in the DeltaBlue test.
This CL brings a 5% improvement in said test by doing
CompressedSigned -> Word32 conversion (instead of
CompressedSigned -> TaggedSigned -> Word32).
There seems to be room for optimizations doing more specialized conversions
regarding representation changes.

Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

Update v8 files / build config accordingly.
- There's now a new library in third_party/inspector_protocol,
bindings/bindings.h, which is configured much like encoding/encoding.h.
It doesn't have much stuff in it yet, but will soon get more code
that would otherwise need to go into jinja templates.
It also comes with a new test, only a smoke test thus far.

to make it easier for devs to look at it, and to create new test cases.
Combined direct decompression & compression tests since they can be
summarized with a for loop in just one test that tries out
all the combinations.
Also created 'global' accesses to stop repeating them in every test.
Same for compression and decompression ops.
Added EXPECT in test cases that had none.
Added dots after comments.

Calling FindIndexInScript performs a linear search on the script functions and can
take considerable time. With Bytecode flushing we will lose the function_literal_id
and have to call FindIndexInScript if we ever recompile the flushed function. This
can take a significant proportion of the recompilation time and has caused regressions
in rendering times for some web applications (e.g, 395ms in FindIndexInScript for 132ms
spent lazily re-compiling code).
To avoid this, add function_literal_id back into the SFI and remove it from
UnoptimizedCompileInfo. This will slightly regress memory usage (particularly
in cases where many of the SFIs are compiled), however it means we can remove
the FindIndexInScript function and avoid these long-tail regressions when
bytecode is flushed.

API calls made via the CallApiCallback builtin, which is used from the
ICs and optimized code, are currently misattributed to the wrong counter
InvokeFunctionCallback instead of FunctionCallback. In addition we don't
use the C trampoline when only runtime call stats are enabled, but the
Chrome DevTools profiler is not active, which means that these calls
will not be attrituted properly at all, and that had to be worked around
using all kinds of tricks (i.e. disabling fast-paths in ICs when RCS is
active and not inlining calls/property accesses into optimized code
depending on the state of RCS).
All of this was really brittle and only due to the fact that the central
builtin didn't properly check for RCS (in addition to checking for the
CDT profiler). With this fix it's now handled in a central place and
attributed to the correct category, so user code doesn't need to worry
about RCS anymore and can just call straight into the fast-path.
Drive-by-fix: Do the same for AccessorInfo getter calls, which share the
core hand-written native code with the API callback logic.

Currently, decompression elimination may reduce phis by pushing decompressions in the value inputs of the phi "down" and replacing it by a single decompression following the phi node. Because of the way that the replacement is currently done, other reducers in the same phase will not generally get a chance to revisit the modified phi.
In the specific case of v8:9335 this blocked an additional optimization in CommonOperatorReducer from being applied, causing the overall load elimination test to fail.
This CL fixes the replacement behavior in decompression elimination to also allow for revisitations of the modified phi node.

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

would break all callers as the names would no longer match.

This was done mostly automatically using this command:

perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.

Provide a global memory controller used to compute limits for combined
on-heap and embedder memory. The global controller uses the same
mechanism (gc speed, mutator speed) and growing factors as the regular
on-heap controller.
Rely on V8's mechanisms for configured state that stops shrinking the
limit.

This CL changes the existing TorqueError struct into a more general
TorqueMessage by adding a "kind" enum. The contextual for lint errors
is removed and replaced by a list of TorqueMessages.
A MessageBuilder is introduced to help with the different
combinations of present information and method of reporting. A lint
error with custom SourcePosition can be reported like this:
Lint("naming convention error").Position(<src_pos_var>);
While a fatal error, with CurrentSourcePosition can be thrown
like this:
Error("something went horrible wrong").Throw();
This approach is both backwards compatible and should prove flexible
enough to add more information to messages or add other message kinds.

DocumentSymbol responses provide all symbols (macros, classes, etc.)
in a given document. The LSP standard evolved over time and supports
two different kind of responses here:
- A simpler one, that is a plain list of all the symbols
- A more detailed one, allowing a hierarchy of symbols. For example
a class symbol has a list of field/method symbols attached. This
is used by editors to build hierarchical outline views.
For now, the simpler response is chosen as its also used for
workspace wide symbol searches.
This CL adds the necessary boilerplate so the actual implementation CL
is easier to review.

This CL adds navigation support for labels in "goto" statements.
Similar to labels listed in the "otherwise" clause of call expression,
definitions of such a label can be found in two places:
- The signature of the current macro.
- A label block of a "try" statement that surrounds the "goto".

Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.
Patchset 1 was auto-generated by using this clang AST matcher:
callExpr(
callee(
cxxMethodDecl(
hasName("start"),
ofClass(hasName("v8::internal::Vector")))
),
argumentCountIs(0))
Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

This CL implements the first set of diagnostic notifications.
When Torque compilation fails, the language server translates the
Torque error into a diagnostics notification and pushes it to the
client.
Note that per specification, the server is responsible to manage the
state of all published diagnostics. This means that the server is
also responsible for clearing out previous notifications if they
become stale.

The Torque compiler makes heavy use of scoped globals (contextuals).
This created a problem for the design of the compiler interface:
- Either the compiler provides all the necessary scopes itself,
disallowing callers any access to the contextuals, which might
contain data the caller is interested in (such as the
compilation result).
- Or the caller provides all the necessary scopes.
This design was fine when the compiler executable was the only user.
With the recent addition of unit tests and the language server, this
interface became brittle, as missing scopes are only detected at
runtime.
This CL refactors the compiler interface to not leak contextual
scopes past the interface boundary. Content of contextuals is
collected and returned, providing access for the caller and freedom
to either use the data directly or move it into the callers own scopes.

This is a reland of 251d1623f3
The reland fixes ASAN component builds by adding RTTI build config to both
torque executables. Big thanks to sigurds for finding the fix.

Previously we'd need to eagerly compile upon access to function.length for a
lazy function. The preparser already computes function.length, however, so we
can store that information in the already available preparse data.

MicrotasksScope has accidentally ignored the given MicrotaskQueue instance
when it's scoping out. That confused the embedder to start using the non

This is a reland of 3bd49f9b90
The issue on the windows bot is apparently a compiler bug in MSVC related to
move construction. The fix seems to be to change the order of the fields in
"JsonParseResult" (go figure).
Drive-by-change: Fix LS on windows by emitting correct line endings and
enabling exceptions for the LS executable as well.

The {remaining_uncommitted_code_space} method is only used for testing.
This CL removes it, and replaces all uses by {committed_code_space}.

We would only increment write barrier counters from the the MacroAssembler's
RecordWrite method which is only used in limited cases. Instead, we should
increment it inside the RecordWrite stub, this way we catch all uses, including
WASM.
Also, we had a static counter aimed at telling us how many barriers exist in
generated code, as opposed to how many are executed. This counter was not
functional since the compiler isn't aware of counters at the moment. Let's just
remove it to avoid confusion.

Locks for compilation state callbacks and for the native module are
again taken one after the other. As a consequence, publishing compiled
Wasm code again happens in parallel. Compile times are now comparable to
before lazy hints were enabled.
