invariant

Immortal immovable roots must be allocated on the first page of the space.
If serializing the root list exceeds the first page, immortal immovable root
objects might end up outside of the first page. That could cause missing
write barriers.
We now iterate the root list twice. The first time we only serialize immortal
immovable root objects. The second time we serialize the rest.

A startup snapshot is considered cold when it does not contain any
function code. We can now create a warm startup snapshot from a cold one
by running a warm-up script. Functions exercised by the warm-up script
are compiled and its code included in the warm startup snapshot. Side
effects caused by the warm-up script does not persist.

Updates cctest.status and also updates the test
cctest/test-serialize/SerializeInternalReference to return success when
FLAG_ignition is true. This test tests for internal references and is not

Previously, optimization has been disabled because of an assertion
failure, which requires the context to be linked into the weak native
context list of the heap.

Changes include:
- better test coverage for builds with snapshot
- write snapshot blobs to buffer instead of test serialization files
- renamed tests

This is a pure refactoring and renaming of methods in the compiler API
with the goal to increase readability. Also the compiler API is moved to
the top of the file, as it is the central piece in that file.

We currently use the outdated contexts list provided by the serializer
to update the receiver (the global proxy) in script contexts. However,
this is not actually necessary, since the global proxy is passed to the
deserializer and replaced as we deserialize.
Originally, the outdated contexts list is to update the global object
field in contexts. This was necessary since at the time the deserializer
creates the native context, the global object has not yet been created.
But the global proxy already exists.

Previously all contexts had a link to the global object, but what is
required in most cases (except for the global load, store and delete
case) is the native context.
This also removes the second dummy global object that was still linked
to every native context. We will add a different mechanism to ensure
that builtins do not pollute the actual global object during
bootstrapping.
Drive-by-fix: Unify some MacroAssembler magic and drop obsolete stuff.

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
