To avoid accidental code that calls stubs without emitting proper
(deopt-id, deopt-env) metadata, we enforce that it's always present for
stub calls and add another GenerateNonLazyDeoptableStubCall for cases
where it's intentionally omitted.
The environment has in many cases been still emitted before, due to the
usage of `pending_deoptimization_env` though we make code pass it
explicitly (just as the deopt-id). We may want to consider deprecating
this `pending_deoptimization_env`.

This class is used during summary linking to do some basic resolution
of ASTs reconstituted from summaries. To prepare for some resolution
work I have in the pipeline, I need to ensure that resolution always
has access to a properly initialized FlowAnalysis object; this rework
makes that possible.
Previously, the lifetime of the AstResolver class was inconsistent;
some callers created one for each AST node to be resolved, and others
shared a single instance for resolving many loosely related nodes.
Now we consistently allocate a fresh AstResolver each time resolution
is needed; this allows AstResolver to use late fields to lazily create
the visitors it needs for resolution.
Also, previously the API for AstResolver was a single resolve() method
with a complex set of behaviors to allow it to handle all the use
cases. Now there are three simpler methods to handle the three use
cases (resolveAnnotation, resolveConstructorNode, and
resolveExpression).

The "RunWithMutatorsStopped" wrapper is used in places where the invoked
callback can cause deoptimization of code. It should therefore ensure
it's running with a "deopt safpoint operation scope" to ensure mutators
are stopped at well-defined places that allow lazy-deopt.

The optimizing compiler can insert box instructions at various places
during the optimization pipeline. There is no guarantee that a box
instruction will get a proper (deopt-id, deopt-env) assigned to it - in
many places it will not.
Furthermore StoreInstanceField's into "unboxed fields" might cause
box allocations to happen. Those stores might also not have deopt
information associated with them.
In general we require stackmaps when allocation slow paths go to runtime
and cause GC. If GC throws OOM we theoretically would also need deopt
information in order to populate correct catch-entry state. Though OOM
is uncommon and the VM could decide to ignore the top-frame - if it's
missing deopt information - since box allocations aren't something
users are in control of (as opposed to user-allocated objects inside
try/catch).
=> This CL makes box allocations go to a runtime entry that doesn't
support lazy-deopt. While being in those runtime entries the mutators
will also not participate in "deopt safepoint operation" requests.

This extends the existing safepoint operation mechanism by allowing to
perform two different operations:
* "gc safepoint operations": All mutators are stopped at places where
it's safe to GC. It therefore requires stackmaps to be available for
all optimized mutator frames.
* "deopt safepoint operations": All mutators are stopped at places
where it's safe to GC, but also safe to lazy-deopt mutator frames.
It therefore requires deopt-id/deopt-info to be available for all
optimized mutator frames.
Mutators can be asked to block for any of those two safepoint operations.
If a mutator is at a place where its safe to GC it will respond to "gc
safepoint operations" requests, if a mutator is additionally at a place
where it's also safe to lazy-deopt it will respond to "deopt safepoint
operation" requests.
Depending on how the runtime was entered (which is tracked via the
[Thread::runtime_call_deopt_ability_] value) - the mutator might
participate in both or only in gc safepoint operations.
During the start of a "deopt safepoint operation", the safepoint handler
will request all threads to stop at a "deopt safepoint". Some threads
might first want to initiate their own "gc safepoint operation"
(e.g. due to allocation failure) before they reach a "deopt safepoint".
We do allow this by letting the safepoint handler own a "deopt safepoint
operation" but still participate in other thread's "gc safepoint
operation" requests until all mutators are checked into places where
it's safe to lazy-deopt at which point the "deopt safepoint operation"
also owns a "gc safepoint operation".
In order to facilitate this, the Thread's safepoint_state will be
extended to consist of the following bits:
* AtSafepoint
* SafepointRequested
* AtDeoptSafepoint
* DeoptSafepointRequested
* BlockedForSafepoint

As a pre-requisite of partitioning our safepoints into "gc only
safepoints" and "lazy-deopt'able safepoints" we'll let mutators keep
track of whether a runtime call into the VM is deoptable.
A mutator is lazy-deopt'able except for one particular case: When the
mutator calls into the VM from a place where no deopt-id/deopt-env
gets recorded (e.g. StoreInstanceField's box allocation goes to
runtime).
If a mutator is in the VM in a non-lazy-deopt'able state, it cannot call
out to the embedder, transition from "vm" to "native" state, ...
A future change will make new non-lazy-deopt'able runtime entries taking
advantage of this CL.

There was a rare mismatch between arguments and parameters when
inlining a constructor body.
The full arguments at the call site of a constructor body (always in a
generative constructor factory) and the parameters at inlining would
not agree on needing a 'box' for the constructor's closed-over mutated
variables (parameters and locals) when the box was needed only for
locals closed over in an assertion.
The fix is to make the condition for accepting a box match the test
for generating the box in the caller.

Safari has a bug that makes it a syntax error for a function name
to overlap with names of parameters in functions with default
parameter values.
This CL changes DDC to generates code to circumvent this issue
when emitting top-level methods. Fortunately, the Safari bug
doesn't trigger with ES6 methods, so we don't need to do anything
for Dart instance methods.
The only other occurrence of named functions in DDC are
`function*` generators that we emit. Those take no arguments,
so we don't need any additional renaming there.

The compounds transformation converting fields into getters and setters
now retains the annotations on the getters so that they can be read
during recompilation.
This splits up `_replaceFields` into `_findFields` and `_replaceFields`.
`_findFields` works for both transformed and non-transformed compounds.
This splits up `_compoundClassDependencies` out from
`_checkFieldAnnotations`. The former is run on all compounds
transitively reached from the compounds being compiled, the latter only
on the compounds being (re)compiled.
`manualVisitInTopologicalOrder` now visits compounds from all libraries,
not just the ones in the libraries being (re)compiled. It is responsible
for filling the `compoundCache` in topological order. And, this CL
introduces the `InvalidNativeTypeCfe` to support processing compounds
with invalid fields, which might be nested later in other compounds.
