- Introduce new struct AsyncGeneratorRequest, which holds
information pertinent to resuming execution of an
AsyncGenerator, such as the Promise associated with the async
generator request. It is intended to be used as a singly
linked list, and holds a pointer to the next item in te queue.
- Introduce JSAsyncGeneratorObject (subclass of
JSGeneratorObject), which includes several new internal fields
(`queue` which contains a singly linked list of
AsyncGeneratorRequest objects, and `await_input` which
contains the sent value from an Await expression (This is
necessary to prevent function.sent (used by yield*) from
having the sent value observably overwritten during
execution).
- Modify SuspendGenerator to accept a set of Flags, which
indicate whether the suspend is for a Yield or Await, and
whether it takes place on an async generator or ES6
generator.
- Introduce interpreter intrinsics and TF intrinsic lowering for
accessing the await input of an async generator
- Modify the JSGeneratorStore operator to understand whether or
not it's suspending for a normal yield, or an AsyncGenerator
Await. This ensures appropriate registers are stored.
- Add versions of ResumeGeneratorTrampoline which store the
input value in a different field depending on wether it's an
AsyncGenerator Await resume, or an ordinary resume. Also modifies
whether debug code will assert that the generator object is a
JSGeneratorObject or a JSAsyncGeneratorObject depending on the
resume type.

Previously code view was set using innerHTML. This would cause problems
for html characters in the code -- in particular, '<' without a space
after it would start new HTML tags, and the code following it wouldn't
be visible.
Now, the source text is set using textContent, which doesn't parse the
value as HTML and implicitly escapes any HTML characters in the code.

The int64-lowering lowers return nodes which return one int64 value into
a return node which returns two int32 values. For this lowering it has
to adjust the input count of the return operator.
The existing code assumed that if the signature of a function said that
the return type is int64, then all return nodes have int64 inputs.
However, with a recent CL we also introduced void returns. With this CL
I check if the number of inputs of a return node changes with the
DefaultLowering, and only if the number of inputs changes, then I check
if I also have to change the operator of the return node.

Now that Ignition has the dedicated TestTypeOf operator, there's not
really a point in doing the typeof with abstract/strict equal combining
in TurboFan anymore. In fact it's counter-productive to do so, as it
might try to cover typeof comparisons in cases where it's better to just
compute the typeof once, i.e.:
let x = typeof a, y = typeof b;
if (x === y) {
if (x === 'string') {
...
}
}
Here we would combine the second comparison into an ObjectIsString, and
still compute the typeof a.

When we call from TurboFan to a CSA or C++ builtin, we can avoid the
ArgumentsAdaptorFrame in case of a parameter arity mismatch by just
filling up missing arguments with undefined or removing additional
arguments on the call site already. This is safe for CSA/C++ builtins,
since those that care about variable arguments are marked with the
kDontAdaptArgumentsSentinel.

A couple bugs had led code in one Context to be able to lead to
estimated memory usage in another Context, even in cases that should be
easy to detect.
- Ensure that the pointer to the next context is nulled out while
recursing over the portion of the heap. It seems like there was
previously some code to do this partway, but the nulling part
was left out.
- Skip including maps in the understanding of the Context estimated
size, as the maps are shared between Contexts and may be reachable
from other Contexts
