The primary purpose of this is to untangle a circular dependency
objects.h -> handles.h -> objects.h. Most compilation units only
need message-template.h, without the rest of messages.h.
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.

Change the way that the (internal) await closures store the link to the
generator object by introducing a dedicated AwaitContext, which stores
the generator object into the extension slot (instead of misusing a
regular FunctionContext here). Also unify the allocation+initialization
of these contexts in the await-related builtins (both for async functions
and generators).
The rationale behind this is that for (zero-cost) async stack traces, we
will need to dig into these contexts and we can do better checking with
a dedicated instance type there. As an additional benefit, we save one
word per await context, since we just use (the otherwise unused) extension
slot to remember the generator object. As yet another benefit we will
never accidentally use any of these contexts in the regular scope chain
lookups, meaning we can also catch bugs there. And last but not least
the objects printing machinery understands these contexts now and can
even print the generator object for AwaitContexts for short printing,
which is really valuable for debugging.

easier to debug this (for V8 developers). It's not observable to

change TurboFan to consistently bailout when it sees an array buffer
that was previously neutered, so that the generic path / builtins are
again the chokepoints for the spec violations (the fact that we don't
always raise exceptions when we see a neutered array buffer), except
for the ArrayBufferView accessor inlining in the JSCallReducer, where
we still turn the values into zero (because we don't have access to
a CALL_IC speculation guard in the common case).
This also removes the ArrayBufferWasNeutered simplified operator, and
does regular LoadField + Number bitwise operations instead, which is
good enough and allows us to get rid of a lot of unnecessary complexity.

When switching log files, if a function was selected the timeline would
attempt to draw its ticks and would usually crash. It would also
preserve the selected section of the timeline.
This patch wipes out the current state when loading a new log file,
with the exception of the current mode (Summary, Bottom up, etc). As a
consequence, the timeline size is now calculated in TimelineView.render
so it will always be drawn at the right size.

This adds a new command abstraction for running commands on Android
using dockered devices on swarming.
The new abstraction handles pushing all required files to the device.
The logic used for pushing and running is reused from the perf runner.
This adds only the mjsunit test suite. Others will be handled in
follow up CLs. The suite logic is enhanced with auto-detection of files

Some test cases need an extra resource section for specifying required

Remaining failing tests are marked in the status files for later

Log::MessageBuilder was already escaping most unsafe characters when
they were being logged, but plain backslashes were not. Merely updating
the existing escaping path was not sufficient, as recursion would cause
escape codes to be doubly escaped. This patches refactors the API to
ensure incoming text is escaped exactly once.

This patch ports most of the Intl.Collator from JS to C++.
The Intl.Collator object no longer stores all the resolved
values. Instead these are looked up on demand as part of
Intl.Collator.prototype.resolvedOptions(), saving several words. In
the future, we can cache the result of the resolvedOptions as well.
In this patch, we use ICU to do parsing of the unicode extension in
the bcp47 language tag instead of using a custom extension parser.
This patch also fixes several spec compliance bugs as well.

Previously, Intl.PluralRules was mostly implemented in JavaScript. This
patch moves most of the constructor and parts of other methods to C++.
The size of the Intl.PluralRules object is reduced by not storing
MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits,
MinimumSignificantDigits, MaximumSignificantDigits. Instead these are
looked up from icu::DecimalFormat as required.
Another optimziation is that we don't create the result of
resolvedOptions when the Intl.PluralRules object is constructed, but
instead defer until this method is called. In the future, we may want
to cache the result.
This patch also cleans up several error handling paths that shouldn't
happen with ICU and instead just crashes should it ever happen.

The generate-header-include-checks.py script generates the cc files to
check that headers can be included in isolation. It currently always
writes to all the cc files. This means that after "gclient runhooks",
all these files have to be recompiled.
This CL fixes this by not touching the file if it already contains the
expected content. This avoids hundreds of recompilations after running
the hook.

All status messages will be printed into STDERR and only the results will
continue to be written to STDOUT as documentation suggests. Additionally the
following changes are made:
- on Buildbot each log entry will have a timestamp to make it easy to measure
time between status messages printed by test runner, users will continue to
see just the message itself
- when devil (or any other module) logs error, they will not be interleaved
with our own output since logging module is thread-safe
- critical logs replaced with warning since they do not immediately stop
the test runner
- logging.exception is used for all exceptions to get formatted stack trace

The test driver compares command-line arguments against test names
it finds on disk. Using Python's "fnmatch" for this nicely handles
wildcards, but is relatively slow. For given test names that don't
contain any '*', we can use string equality testing, which is much
faster.
Example: the time to evaluate
tools/run-tests.py --arch x64 --mode release \
$(grep 'object-spread' -l -r test/test262/data/test/ | \
sed -E 's|\.js$||' | \
sed -E 's|^test/test262/data/test/|test262/|')
goes from "I gave up and killed the process after several minutes"
to a couple of seconds with this patch.

The most important point of IWYU (include-what-you-use) is that each
header includes everything it is using, so that whoever includes that
header does not need to additionally include other things.
This CL adds a script which generates files to automatically check this.
It is automatically invoked during "gclient runhooks" if the
"check_v8_header_includes" variable is set. This script generates a
number of .cc files in the "check-header-includes" directory, together
with a "sources.gni" file which lists all the generated cc files. Each
file includes one header.
If additionally the gn args "v8_check_header_includes" is set, this gni
file is included, and all the generated CC files will be compiled. This
will detect violations of the aforementioned IWYU rule.
