Besides avoiding the weird hack of inserting a statement at the 0th
index of the function body, we also avoid allocating (and initializing)
the variable if it's unreferenced (which I'd wager is the common case).

Previously, the class fields initializer function was stored on a
synthetic context allocated variable. This approach had sevaral
problems:
- We didn't know that class literal had fields until after we had
completely parsed the class literal. This meant that we had to go back
and fix up the scope of the constructor to have this synthetic
variable. This resulted in mismatch between parser and preparsed scope
data.
- This synthetic variable could potentially resolve to an initializer
of an outer class.
For ex:
class X extends Object {
c = 1;
constructor() {
var t = () => {
class P extends Object {
constructor() {
var t = () => { super(); };
t();
}
}
super();
}
t();
}
}
In this the inner class P could access the outer class X's initiliazer
function. We would have to maintain extra metadata to make sure this
doesn't happen.
Instead this new approach uses a private symbol to store the
initializer function on the class constructor itself.
For the base constructor case, we can simply check for a bit on the
constructor function literal to see if we need to emit code that loads
and calls this initializer function. Therefore, we don't pay the cost
of loading this function in case there are no class fields.
For the derived constructor case, there are two possiblities:
(a) We are in a super() call directly in the derived constructor:
In this case we can do a check similar to the base constructor check,
we can check for a bit on the derived constructor and emit code for
loading and calling the initializer function.
This is usually the common case and we don't pay any cost for not using
class fields.
(b) We are in a super() call inside an arrow function in the derived
constructor:
In this case, we /always/ emit code to load and call the initializer
function. If the function doesn't exist then we have undefined and we
don't call anything. Otherwise we call the function.
super() can't be called twice so even if we emit code to load and call
the initializer function multiple times, it doesn't matter because it
would have already been an error.

In snapshots with several contexts, some contexts may not reference
function or object templates, and therefore would not require external
references for deserialization. However, function and object templates
are deserialized with the isolate as part of the partial snapshot cache,
so we would need these external references even if we only use contexts
that don't need them.
With this patch, we use a fallback in case no external references are
provided. This way, we only run into issues when we actually call native
callbacks.

compiler gets initialized at the beginning of the code section.
If we detect that compilation has not been started because there was no

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`).

As a side effect, this refactoring enforces right-trimming

BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.
