ThrowableStringBuilder is a thin wrapper around StringBuilder to map
results from the try_* methods to a throw completion. This will let us
try to throw on OOM conditions rather than just blowing up.

This regex is pessimistic, so there might be more files that don't
actually use anything from the stdlib.
In theory, one might use LibCPP to detect things like this
automatically, but let's do this one step after another.

This reverts commit 032664332b.
Now that AK::years_to_days_since_epoch has acceptable performance, we
can go back to the "easy" way of computing the unix epoch time.

Implements: tc39/proposal-temporal@261692a
In order to remove the call to to_positive_integer() there neeeded
to be a change of return type from ThrowCompletionOr<Value> to
ThrowCompletionOr<double>.
This is one of the changes that will come anyways with the following
commit: tc39/proposal-temporal@11aad40. :^)
Default-constructing the m_value Completion made it have an undefined
JS value when not overridden in a constructor, such as the conditional
initialization in Optional(Optional<JS::Completion> const&).

We return early from the DateTimeFormat constructor to avoid crashing on
assertions when the CLDR is disabled. However, after commit 019211b, the
spec now mandates we assert the time zone identifier is valid. The early
return resulted in this identifier being an empty string.
GCPtr can be null so it's not safe to assign it to a NonnullGCPtr unless
you know it to be non-null.
This exposed a number of wrong uses in LibWeb which had to be fixed as
part of this change.
This constructor was easily confused with a copy constructor, and it was
possible to accidentally copy-construct Objects in at least one way that
we dicovered (via generic ThrowCompletionOr construction).
This patch adds a mandatory ConstructWithPrototypeTag parameter to the
constructor to disambiguate it.
It was possible for the generic ThrowCompletionOr constructor to
"copy-construct" a JS Object when instantiating a ThrowCompletionOr
via e.g `return *object;`.
This happened because it chose the Object(Object& prototype) constructor
which will be removed in a subsequent commit. It was not easy to debug.
As a first step towards avoiding this in the future, the generic
ThrowCompletionOr constructor now takes the value as a const reference.
Note that this still keeps the old behaviour of putting things in std by
default on serenity so the tools can be happy, but if USING_AK_GLOBALLY
is unset, AK behaves like a good citizen and doesn't try to put things
in the ::std namespace.
std::nothrow_t and its friends get to stay because I'm being told that
compilers assume things about them and I can't yeet them into a
different namespace...for now.
