Progress indicator calculates the percentage using the estimated amount of
tests.
When base tests produce more tests or when testrunner filters some tests, the
percentage terminates over 100% or under it.
This CL adds an informative message about how the percentage behaves.

The StackTraceFrame object will be used in a future CL to replace
StackFrameInfo as the object returned by the inspector API, as well
as the object used in the stack_frame_cache.
The object itself is a simple wrapper around a reference to a
FrameArray plus an index, as well as a reference to a
StackFrameInfo object that will get lazily initialized.
This is the first step towards unifying stack trace representation
and collection.

Using test generators meant that we had to remove the progress indicator since
the total number of tests weren't known before-hand.
This CL implements a progress indicator using test number estimations.
cctest and unittests progress indicator is accurate, however estimating
means the progress will terminate over 100% in big test suites and sometimes
under 100%.

Testrunner test-suite doesn't have automated tests for the Fuzzer. A significant
change for the testrunner may break the fuzzers. We don't have a way to catch
even the syntax errors for the fuzzer before landing CLs.
This CL creates a rudimentary test-suite that runs the fuzzer without any tests
to see if APIs still work as intended.

HeapObject::SizeFromMap() was too large to get inlined anyway.
HeapObject::IsFoo() predicates should be implemented in foo-inl.h,

This patch also fixes up includes: dropping unnecessary ones from
object-inl.h, and adding them in other places that previously
relied on getting them transitively.

V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.
This CL converts the test-suites to load tests during the test run in parallel.
After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.
This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

Class positions is a struct that stores the start and end positions of a class
literal. It is stored both on class objects, and the template used to
instantiate class objects.
The template is reachable from the bytecode array and therefore serialized by
the startup serializer. Class objects are context-dependent and therefore

This requires honoring the instance size of the object stored in the
map for JSObject. To do this, allocation is now split into two
instrinsics, one that calculates the base size of the allocated object
(%GetAllocationBaseSize) and one that actually allocates (%Allocate).
In the process, remove objects.tq, which only existed to contain a
macro to fetch the default JSObject map, which is functionality that
is now in the JSObject class constructor.

Now, the CodeAssembler can annotate Nodes with SourcePositions.
SourcePositions themselves get a new mode "external," in which
they get a file_id, line and column. The file_id is currently
maintained in the isolate, mapping to strings for filenames.
Additionally, inlining information is ignored at this point,
but in the long run I'd like to recognize calls to different
CSA functions as manual inlinings.
At this point, if you want to see the results in tools like GDB,
you'll need to build without clang, and use the GCC toolchain.
GN flag is_clang=false will do the trick.

With the changes in this patch, it is now possible to add methods to
both Torque's class and struct types. As a special case, "constructor"
methods are used to initialize the values of classes and structs when
they are constructed.
The functionality in this patch includes:
- The refactoring of class- and struct-handling code to share field
and method declaration code between both.
- Addition of the "%Allocate" intrinsic that allocates raw bytes to be
allocated from the V8 GC's NewSpace heap as the basis for freshly
created, initialized class objects.
- An implementation of a CallMethodExpression AST node that enables
calling methods and constructors, including special handling of
passing through the "this" pointer for method calls on structs by
reference. The syntax for struct construction using "{}" remains as
before, but now calls the struct's matching constructor rather than
implicitly initializing the struct fields with the initialization
arguments. A new syntax for allocation classes is introduced: "new
ClassName{constructor_param1, constructor_param1, ...}", which
de-sugars to an %Allocate call followed by a call to the matching
constructor.
- class constructors can use the "super" keyword to initialize their
super class.
- If classes and struct do not have a constructor, Torque creates a
default constructor for them based on their field declarations,
where each field's initial value is assigned to a same-typed
parameter to the the default constructor. The default constructor's
parameters are in field-declaration order, and for derived classes,
the default constructor automatically uses a "super" initialization
call to initialize inherited fields.
- Class field declarations now automatically create ".field" and
".field=" operators that create CSA-compatible object accessors.
- Addition of a no-argument constructor for JSArrays that creates an
empty, PACKED_SMI_ELEMENTS JSArray using the machinery added
elsewhere in this patch.

TestSuite has a static method LoadTestSuite that should properly configure the
TestSuite instance (i.e. loaded status files and tests), however the method
leaves some configuration logic to the caller.
The leaky abstraction causes the caller to do a bunch of loading operations (see
the removed methods in base_runner.py).
This CL isolates the TestSuite loading logic to the static method only.
This is a refactoring only change without any intended logical changes.

Class declarations support structured heap data that is a subtype of
HeapObject. Only fields of Object subtypes (both strong and weak)
are currently supported (no scalar fields yet).
With this CL, both the field list macro used with the C++
DEFINE_FIELD_OFFSET_CONSTANTS macro (to make field offset constants) as
well as the Torque "operator '.field'" macros are generated for the
classes declared in Torque. This is a first step to removing the
substantial amount of duplication and boilerplate code
needed to declare heap object classes.
As a proof of concept, and handful of class field definitions,
including those for non trivial classes like JSFunction, have been
moved to Torque.

- Input to the search box was not reliably working, because
the SVG keydown handler was attached to the window and its
repeat-key detection was supressing key events.
- Selecting the input of a node via keys 1-9 did not select the

This is purely a renaming change. The ES spec uses the term 'detach'

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

- 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.

This patch gives DescriptorArray its own visitor id and its
own layout that is independent from the layout of WeakFixedArray.
This allows us to use raw 16-bit integers for keeping track of
the number of descriptors (total, non-slack, and marked).
As a side-effect, we save one word per descriptor array on 64-bit.

We recently changed embedded builtins to be emitted as raw assembly
files during the build process in order to support MSVC (which doesn't
support inline assembly on x64). Ninja uses ml.exe / ml64.exe as the
assembler on all Windows builds (msvc & clang); these unfortunately
don't support large data streams well and can take over 5 minutes for
embedded.S.
With this CL we work around this by going back to inlined assembly for
clang Windows builds.

Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS
since that is called when we are compiling the native context independent SharedFunctionInfo
and the WasmModuleObject requires a native context. Instead save the members required to
create the object in the AsmWasmData and create it during module instantiation. Note:
since the Wasm module is an implementation detail for asm_wasm code and isn't exposed,
this doeesn't have semantic change for asm.js code.
As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated
struct. Some logic is also moved from module-compiler to wasm-engine to make the
seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.

This enables more seamless interop between Torque and CSA:
Since CodeStubAssembler can now inherit from the Torque base namespace,
macros defined in the base namespace can be used in CodeStubAssembler
macros, even without qualification.
At the same time, macros in the base namespace can refer to
CodeStubAssembler macros. The only new limitation is that types defined
in code-stub-assembler.h cannot be referenced in the signature of macros
defined in the base namespace, since this would produce a cyclic header
dependency. A work-around for this woud be to put such types (like int31
in this CL) into a separate header included by both. I (mis-)used
code-assembler.h for that.
Another side-effec is that types and enums defined in CodeStubAssembler
have to be accessed in a qualified way from Torque.
Other assemblers can now inherit from their Torque equivalent, so
porting macros into the corresponding Torque namespace doesn't require
any change to the existing use-sites.
To avoid C++ ambiguities, the Torque-generated assemblers must not define
anything also defined in Code(Stub)Assembler. This includes the type
aliases for TNode, PLabel, ...
My workaround is to qualify everything in the generated C++.
As a drive-by fix, I had to change the formatter to avoid a situation
where it doesn't compute a fixed point: putting a keyword at the
beginning of a line removes the '\s' in front of it, so I replaced that
with '\b'.

- Add WeakFactory.prototype.makeRef
- Implement the "keep during job" behavior for WeakRef constructor and deref().
- Here we keep the targets alive longer than until the end of the job
(microtask), contradicting the spec. However, this is probably the indended
behavior, see https://github.com/tc39/proposal-weakrefs/issues/39 .

We define a TestFailedError exception and raise it when we can reliably detect
that a test has crashed. All other exceptions are treated as infra failures and
are captured by the try-catch clause in MainWrapper function.
This also fixes all tests in run_perf_test.py, run_tests_test.py and makes sure
that both are run on any changes in tools directory.

change "Also forces all non-trampoline RelocInfo ByteArrays for builtins
to be generated into RO_SPACE."
Creates a single RelocInfo to be used by all builtin trampolines and
stores it as a root. All trampolines then substitute this for their
trampoline at generation time with DCHECKs to make sure it is
identical.
On x64, this results in the OLD_SPACE part of the startup snapshot
decreasing in size from 165656 to 130808 (-34848) bytes and RO_SPACE
(in the read-only snapshot) increasing from 31248 to 31272 (+24) bytes.

This also includes ports of Array.p.toString and Array.p.toLocaleString.
Many parts of the old JS implementation are preserved, because
TypedArray.p.join still relies on it. These will be removed once
TypedArray.p.join is ported to Torque.
To simplify implementation, special handling of extremely sparse arrays
has been removed.
Performance improvements vary by array size, elements, and sparse-ness.
Some quick numbers and graphs are here:

The primary purpose of this is to untangle a circular dependency

Bonus: change the enum to an enum class for improved type safety.

The implicit parameter syntax adds a second parameter list
before the explicit parameter list when declaring macros, builtins and
runtime functions:
extern macro MyMacro(implicit a: Smi)(b: Oddball);
when calling the macro, only the formal parameters can be provided
at the call site. The implicit parameters are implicitly looked-up
by name in the scope of the call and prepended to the explicit parameter
list. The values that are found by name for each implicit parameter must
be castable the corresponding implicit parameter type:
MyMacro(Null); // Error, a is not defined
...
const a: Smi = 0;
MyMacro(Null); // OK
...
const a: Object = 0;
MyMacro(Null); // Error, a has wrong type
For external macros, builtins and runtime functions, the formal
parameter list expected on the C++ side is the concatenation of the
implicit and explicit parameter lists.
As a drive-by: fix the formatting of typeswitch statements in the
the presence of deferred-marked blocks and funky white space.

This JSAsyncFunctionObject represents the implicit generator object
inside of async functions, and also holds the outer promise for the
async functions. This in turn allows us to get rid of the .promise
in the Parser / BytecodeGenerator completely, and will make it
possible to build zero-cost async stack traces independent of the
concrete synchronous part of the stack frame (which currently breaks
in Node.js).
In the bytecode all the async function operations now take this new
JSAsyncFunctionObject instead of passing both the .generator_object
and the .promise, which further simplifies and shrinks the bytecode.
It also reduces the size of async function frames, potentially making
the suspend/resume cheaper.
This also changes `await` to use intrinsics instead of calling to
special JSFunctions on the native context, and thus reduces the size of
the native contexts.
Drive-by-fix: Introduce a dedicated JSCreateAsyncFunctionObject operator
to TurboFan.

The MapIterator protector protects the original iteration behaviors of
Map.prototype.keys(), Map.prototype.values(), and Set.prototype.entries().
It does not protect the original iteration behavior of
Map.prototype[Symbol.iterator](). The protector is invalidated when:
* The 'next' property is set on an object where the property holder is the
%MapIteratorPrototype% (e.g. because the object is that very prototype).
* The 'Symbol.iterator' property is set on an object where the property
holder is the %IteratorPrototype%. Note that this also invalidates the
SetIterator protector (see below).
The SetIterator protector protects the original iteration behavior of
Set.prototype.keys(), Set.prototype.values(), Set.prototype.entries(),
and Set.prototype[Symbol.iterator](). The protector is invalidated when:
* The 'next' property is set on an object where the property holder is the
%SetIteratorPrototype% (e.g. because the object is that very prototype).
* The 'Symbol.iterator' property is set on an object where the property
holder is the %SetPrototype% OR %IteratorPrototype%. This means that
setting Symbol.iterator on a MapIterator object can also invalidate the
SetIterator protector, and vice versa, setting Symbol.iterator on a
SetIterator object can also invalidate the MapIterator. This is an over-
approximation for the sake of simplicity.
