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
to be pushed to devices, for e.g. load or import statements.
Some test cases need an extra resource section for specifying required
files.
Remaining failing tests are marked in the status files for later
triage.

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.

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

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.

remove these fields from SFI. Uncompiled functions with pre-parsed
scope data now hold an UncompiledDataWithScope that has a pointer to
PreParsedScopeData -- this allows us to also remove the start/end pos
from PreParsedScopeData.

This enables us to reduce both FunctionTokenPosition and

Adds a ReadOnlyRoots class trivially constructable from a Heap* or
Isolate* and which can be obtained from a any HeapObject which provides
access to roots objects that will always be in RO_SPACE. In the longer
term this object will be accessed via a global variable without
requiring an Isolate or using the memory address of a HeapObject to
infer it.
Moves the list macros in heap.h to roots.h and splits some of them into
two parts (read-only and mutable).
Convert cases of heap_object->GetHeap()->root_accessor() to
heap_objects->GetReadOnlyRoots().root_accessor().

Adds a instance types for each HashTable subtype, rather than reusing
HASH_TABLE_TYPE. This allows us to check for these types by checking
the instance type directly, rather than by comparing against the map in
the root set.
Also, as a drive-by, do the same for SCRIPT_CONTEXT_TABLE_TYPE, and use
instance type checks rather than map checks for Context types.
This is a good general clean-up, but in particular is intended for
GetIsolate removal.

All Object::Print functions now take an Isolate* parameter. Various
XX::XXPrint functions now take an Isolate if it's needed rather than
calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather
than DECL_PRINTER.
The _v8_internal_Print_ function (intended for use in gdb) now uses
Isolate::Current() to get hold of an Isolate.
Reduces the GetIsolate and GetHeap count by 9 and 5 respectively.
Also removes unneeded gdb/lldb macros (along with their support
functions), jfv, jfm, jda and jta, since job does the same thing.

For now we keep params since NewSloppyArguments uses it to figure out how to structure the arguments object. We should be able to only keep params in case we have a special case though. E.g., leaf functions with no duplicate parameters don't need special treatment. Or we simply encode the parameter index for each context slot. (I'm not sure duplicates need special treatment.)

this objective has no real value, and we already store some internal

This CL updates the d3.js library to version 5.4. The most notable
change is that the library can now distinguish between click and drag
events if an element supports both selection via click and displacement
via drag.
Curiously, npm created a 'package-lock.json', which is ~500 lines, and
which is supposed to be checked into the repository according to documentation.

This is a reland of 91bab5588c
This CL contains two major changes w.r.t to the original CL:
The random state is removed from the Smi root list and we pre-seed the RNG
on each sort with the length of the array.
To cut down on the length of the arguments list and to keep track of the
random state across recursive calls, we move most of the sort arguments into
a FixedArray and reload from the array for each recursion.
Original change's description:

- ContextExtension is probably not needed anymore, since we now always have the

Original CL: https://crrev.com/c/1018468
During code generation, we generate self-references (i.e. references to
the Code object currently being generated) as references to a temporary
handle. When the final Code object has been allocated, the handle's
location is fixed up and RelocInfo iteration fixes up all references
embedded in the generated code.
This adds support for this mechanism to the builtins constants table
builder. CodeObject() is now a new handle pointing to a dedicated
self-reference marker in order to distinguish between self-references
and references to undefined. In Factory::NewCode, we patch up
the constants table.

When internalizing string literals (for quoted strings or property names),
try to create a sliced string of the source string rather than allocating
a copy of the bytes.
This will not work for string literals that contain escapes (e.g. unicode
escapes), and currently does not support two-byte strings.

Also updates VerifyReadOnlyPointers to check that RO_SPACE objects' maps are
also in RO_SPACE. Previously the invariant did not hold for Strings which still
had their maps in MAP_SPACE.

This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:
When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.
The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.
Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

When attributing ticks to a function, we first check if the current pc
matches a section within the dynamic library. If we find a match here,
then we don't continue looking within dynamically generated range
information, e.g. for JS functions and builtins.
This logic breaks when embedded builtins come into play. They live
within the libv8.so shared library, and are found when looking up
statics. But what we really want is to look up the dynamically
generated code-range, which contains more precise information.
In this CL, this case is detected by matching the found symbol name.
If it's the embedded blob, then we continue to dynamic lookup.

This makes testing with random gc stress use the status file entrees
for gc fuzzing as well, since many test cases not suitable for one, are
not suitable for the other.
This also skips two more tests that rely on assert(Un)Optimized, which
is unreliable with gc fuzzing.

Torque production-ready for any non-trivial amount of code, but
landing the prototype as-is will allow for much faster iteration.

adds a runtime flag which makes interpreted frames visible on the
process' native stack as distinguishable functions, making the sampled
