This name makes it clear that the flag (also the variant in the Compiler)
is talking about specializing to the function context instead of i.e. the
native context.

If we do not clear next links during serialization, the
serializer would simply follow those links and serialize
arbitrary objects held by weak cells. This breaks the
invariant in the code serializer, which crashes if it
sees context-dependent objects.

When the page is controlled by a ServiceWorker, the ServiceWorker can return an opaque (non-CORS cross origin) resource response.
We need to treat the messages from such script resource as opaque.

We keep an eye on the recursion depth. Once it exceeds a limit, we serialize
only the object header and size, but defer serializing the object body for
after we have unwound the stack.

Make the parser handle references to "this" as unresolved variables, so the
same logic as for the rest of function parameters is used for the receiver.
Minor additions to the code generation handle copying the receiver to the
context, along with the rest of the function parameters.
Based on work by Adrian Perez de Castro <aperez@igalia.com>.

We shouldn't have shared state between isolates by default. The embedder
is free to pass the same allocator to all isolates it creates.

Add a finalize incremental marking mode for CollectAllGarbage to finalize incremental marking when incremental marking is in progress, but we want a full gc at a given CollectAllGarbage call site.
Default mode for CollectAllGarbage is finalize incremental marking and perform a full GC.

Performance measurements show that the position independent code is
usually slightly faster than the position dependent code, and there
seems to be no noticable regression.
This also gets rid of a lot of support code that was only required to allow
embedding labels into the code stream. And it implies that neither the GC
nor the deserializer need to do anything for jump tables.

External references are encoded as a tuple of type and ID. This
requires both the external reference encode and the decoder to
create a mapping between the encoding and the external reference
table index.
Instead, we simply use the external reference table index as
encoding.
We now also assume that there are no duplicate entries. Existing
duplicates have been removed in this change.

Internal references are absolute addresses into the instruction
stream. Turn them into relative addresses when serializing and
back when deserializing to keep them valid.
