I've seen occasional flakiness in our testing of this feature, but
couldn't pinpoint the reason for it. However, decreasing the frequency
how often we check for changes of the `command.log` and looking at a
larger chunk of the file seems to help (based on running th tests
multiple times).

putIfAbsent uses a closure and the VM allocates a context,
replacing it with ??= which doesn't should be better.
In a previous iteration it was found - with 95% confidence - a
~4ms (~10%) improvement, but for whatever reason those results
cannot currently be reproduced.

Previously, compiler canonicalized Phi instructions which reference
only one value (modulo redefinitions):
v1 = Phi(v2, v2, ..., v2)
This change extends the canonicalization rule to also allow the Phi
to reference itself:
v1 = Phi(v2, v2, ...., v2, v1, ...., v1)
Such Phi instructions may occur in loops when local variable is not
mutated (remains the same on the back-edge).

In the codebase, we have several different interfaces for equality
instance methods on a type T:
- bool Equals(const T&) const;
- bool Equals(const T*) const;
- bool Equals(T*) const;
This CL standardizes on `bool Equals(const T&) const;`, and adjusts any
related functions to match.
TEST=Existing test suites, as this is an internal refactoring.

Expandos no longer accept `Pointer`s and subtypes of `Struct`s

Reland 1: Allow importing `dart:ffi` from `dart:core` with
`--enable-ffi=false`.
Reland 2: Allow the new `_Compound` class to extend `NativeType`. (This
got triggered in this CL on the build because of the import
from `dart:core`.)

The jsshell is used rarely for benchmarking and testing.
Make download of it conditional, at least until it is uploaded
and moved to CPID, to help migration to python3.
To download the shell in a checkout, add
"checkout_javascript_engines": True
to the "custom_vars" in a .gclient solution.

Instead of special-casing the current fields that may have
WeakSerializationReferences, handle WSRs appearing as elements
or properties of objects more generally. This removes existing
special casing and avoids the need for it in case of new
future uses of WSRs.
For artificial nodes being added for dropped
WeakSerializationReference targets, add them as kArtificial nodes
(not kSnapshot) that has the original offset (element) or
name (property). The replacement is added as a kSnapshot node
that has a negative offset with the same magnitude as the
artificial node (element) or ":real_<property name>" (property).
This simplifies the work done in pkg/vm_snapshot_analysis to
use the artificial nodes instead of replacement ones for
reassembling hierarchies and the like.
This CL also cleans up the old SerializerWritingObjectScope
class, both moving it to Serializer::WritingObjectScope and
allowing nesting of WritingObjectScopes with the correct
semantics.
Thanks to this, not only can we recur when under a WritingObjectScope
instead of lifting recursion outside of those scopes, but we can
also create artificial nodes for non-empty per-code object pools and
static call target tables instead of attributing their contents
as supposed elements of the Code object being written.
