The logic for removing while iterating is non-standard and
a left over from a previous index based loop. This patch
replaces it with a standard erase based version.
This fixes a runtime crash with MSVC that invalidates the
iterator and then asserts. This also makes the code safe
in case the last move can be redundant.

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\");");'

Set entries return an array with the value as first and second entry.
As such these are considered key value pairs to align with maps
entries iterator.
So far the return value was identical to the values iterator and that
is misleading.
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.

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.

This reverts commit d30a8fa9b4.
Reason for revert: no-snap test failures here
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20nosnap%20-%20debug/builds/17068
You need to update the whitelist in src/debug/debug-evaluate.cc.
I'm a bit surprised this only happens in no-snap builds.

If the source checkout had 'debug' somewhere in the path name, then
IsDebuggerFile() marked all modules as debug ones, which triggered
an assertion during snapshot generation.

The existance of an `AllowJavascriptExecutionDebugOnly` scope in
`Isolate::ReportPendingMessages()` indicates that the API supports
running arbitrary JS code in a `AddMessageListener` callback.
Currently, this can fail in debug mode: The
`!isolate->external_caught_exception()` condition is checked when
entering API methods inside such a handler. However, if there is
a verbose `TryCatch` active when the exception occurs, this
check fails, and when calling `ToString()` on the exception object
leaves a pending exception itself, the flag is re-set to `true`.
Fix this problem by clearing the flag and the pending exception if
there was one during `ToString()`. This matches the code a few lines
up in `messages.cc`, so the exception state is now consistent
during the callback.
This currently makes a Node.js test fail in debug mode
(`parallel/test-error-reporting`).
