V8 side mechanism for overriding the wasm js APIs.
We will use these to:
- implement the Chrome-side constraints on module size, and throw with more
actionable error messages, while preserving layering.
The old mechansms will be deleted once we update the Chrome side with
this new mechanism.
- implement Chrome-side .compile and .instantiate overrides accepting
Response objects.
We may want to evolve this mechanism into something more general, not
requiring V8 preparation, by replacing the v8-definition with embedder
provided definitions. We're currently exploring if we can expand
"Extras", for instance.

With precise binary code coverage, the reported count is either 0 or 1.
We only report 1 the first time we collect coverage data after the
function has been executed.
Since we do not care about the accurate execution count, we can optimize
the function once it has been executed once.
Also change best effort coverage to be implicitly binary.

We want to restrict structured cloning in Chrome to:
- postMessage senders and receivers that are co-located
in the same process
- indexedDB (just https).
For context, on the Chrome side, we will achieve the postMessage part
by using a mechanism similar to transferrables: the
SerializedScriptValue will have a list of wasm modules, separate from
the serialized data stream; and this list won't be copied cross
process boundaries. The IDB part is achieved by explicitly opting in
reading/writing to the serialization stream. To block attack vectors
in IPC cases, the default for deserialization will be to expect data
in the wasm transfers list.
This change is the V8 side necessary to enabling this design. We
introduce TransferrableModule, an opaque datatype exposed to the
embedder. Internally, TransferrableModules are just serialized data,
because we don't have a better mechanism, at the moment, for
de-contextualizing/re-contextualizing wasm modules (wrt Isolate and
Context).
The chrome defaults will be implemented in the
serialization/deserialization delegates on that side. For the v8 side
of things, in the absence of a serialization delegate, the V8
serializer will write to serialization stream. In the absence of a
deserialization delegate, the deserializer won't work. This asymmetry
is intentional - it communicates to the embedder the need to make a
policy decision, otherwise wasm serialization/deserialization won't
work "out of the box".

This makes it more similar to other handle types (like PersistentBase),
by simply storing an i::Object** cast to T*. This means that it is not
necessary to look up the handle in the eternal handles table to access
the underlying value.
Like the built-in roots (null, etc.), an eternal handle can never be
destroyed, so we don't even need to allocate a separate local handle.
Instead, the Local<T> can point directly at the eternal reference.
This makes Eternal<T>::Get trivial.

This CL renames all occurrences of "internal field" to "embedder field"
to prevent confusion. As it turns out, these fields are not internal to
V8, but are actually embedder provided fields that should not be mucked
with by the internal implementation of V8.

This is basically the minimum viable signal handler for Wasm bounds checks.
It includes the TLS check and the fine grained instructions checks. These
two checks provide most of the safety for the signal handler. Future CLs will
add code range and data range checks for more robustness.
The trap handling code and data structures are all in src/trap-handler, with
the code that actually runs in the signal handler confined to
src/trap-handler/signal-handler.cc.
This changes adds a new V8 API that the embedder should call from a signal
handler that will give V8 the chance to handle the fault first. For hosts that
do not want to implement their own signal handler, we include the option to
install a simple one. This simple handler is also used for the tests.
When a Wasm module is instantiated, information about each function is passed
to the trap handler, which is used to classify faults. These are removed during
the instance finalizer.
Several future enhancements are planned before turning this on by default.
Obviously, the additional checks will be added to MaybeHandleFault. We are
also planning to add a two-level CodeObjectData table that is grouped by
isolates to make cleanup easier and also reduce potential for contending on
a single data structure.

As of version 13, delegates do not need to worry about colliding tags with the
tags reserved by v8, since v8 inserts a "host object" prefix beforehand. Thus

v8 allows the embedder to specify a global template to use when
creating a new context. However, v8 does not use the supplied
template directly when creating the global proxy: it creates a
unique template for each global proxy. However, this is problematic
for remote contexts: functions cannot use strict receiver checks
with the remote context, as the global template will never match
the global proxy.
To fix this, remote contexts now also include a remote global
object in the prototype chain that is instantiated with the global
template. This mirrors the way the global proxy is configured for a
full v8 context, and allows strict receiver checks to work.
