Currently, Number.prototype.toString(radix) often fails to produce the
least significant bit for doubles near zero. For example, for the
minimum double, 5e-324, toString(2) produces "0". This means that a
user cannot reliably get the exact binary or hexdecimal value of a
double from JavaScript using toString.
This patch makes a slight amendment to the DoubleToRadixCString
function, so that doubles where the gap to the next double is 5e-324
(i.e. doubles less than 2**-1021), are represented exactly in binary and
other power-of-two bases, and close to exactly otherwise. It results
in Number.prototype.toString producing the correct binary value for all
doubles.

throw Error('foo') consists of an ExpressionStatement, with a
Throw expression stored within the statement. The source range itself

Add an enum argument to DateTimeConfigurationChangeNotification to
control whether or not to redetect the host time zone. The default value
kSkip doesn't cause redetecting so that callers do not need to change if
they want the current behavior (e.g. Chromium).
Note that the host time zone detection does not work when v8 is run
inside a sandbox as in Chromium so that Chromium detects the host time
zone outside the sandbox before calling
DateTimeConfigurationChangeNotification. OTOH, other v8 embedders may
find it more convenient for v8 to do the host time zone detection on
their behalf. In that case, they can call the function with the new
argument set to value kRedetect.
Test:
With PHP+V8Js on linux, execute:
php -r '
putenv("TZ=Europe/Helsinki");
$v8 = new V8Js();
$v8->executeString("print((new Date(0)).toString()+\"\\n\");");
putenv("TZ=America/New_York");
$v8->executeString("print((new Date(0)).toString()+\"\\n\");");'

As such these are considered key value pairs to align with maps

So far the return value was identical to the values iterator and that

This also adds tests to verify the results and improves the coverage
a tiny bit by testing different iterators.

Currently, because the source float_64_array has an iterator, it hits
the code in the "check_iterator" section of TypedArrayFrom which calls
IterableToList. This builds a temporary PACKED_ELEMENTS array (and boxes
all of the numeric values as HeapNumbers), then uses this as the source
array.
This patch checks if the source array is a TypedArray, and if the iterator
is the built-in one (where we know the iterator's behaviour). If both are
true then it bypasses the creation of this temporary array and uses the
original TypedArray as the source.
This allows it to take advantage of the existing fast code for copying one
typed array to another.

This change added Windows ARM64 ABI support, major things are:
1. Excluding x18 register from any usage because it is reserved as
platform register. Preserve alignment after the change.
2. Fix the assumption of LP64 in arm64 backend. Windows ARM64 is
still LLP64.
3. Stack guard page probe for large allocation on stack.
Reference:
Windows ARM64 ABI:

Previously, DateTimeFormat.prototype.formatToParts returned an object
with the property key 'dayperiod' which is incorrect as per the spec.
This patch updates the property key to say 'dayPeriod', making this spec
compliant.

I have a project that embeds V8 and uses a single `Isolate` from multiple
threads. The program runs just fine, but sometimes the inspector doesn't
stop on the correct line after stepping over a statement that switches
threads behind the scenes, even though the original thread is restored by
the time the next statement is executed.
After some digging, I discovered that the `Debug::ArchiveDebug` and
`Debug::RestoreDebug` methods, which should be responsible for
saving/restoring this `ThreadLocal` information when switching threads,
currently don't do anything.
This commit implements those methods using MemCopy, in the style of other
Archive/Restore methods in the V8 codebase.

When parsing a numeric literal in a line like "a=0x0e+b|0;",
currently the scanner consumes the "e+" part (as it thinks
it's the start of an exponent).
In the ECMAScript lexical grammar HexIntegerLiteral cannot
contain exponents, which means the '+' character should be
parsed as a binary operator.

Adds the builtin Trace and IsTraceCategoryEnabled functions
exposed via extra bindings. These are intended to use by
embedders to allow basic trace event support from JavaScript.
```js
isTraceCategoryEnabled('v8.some-category')
trace('e'.charCodeAt(0), 'v8.some-category',
'Foo', 0, { abc: 'xyz'})
```
