Timer events and perhaps other events are throttled when a Chrome tab
is in the background or not visible. This may be causing flaky timeouts
in Dart web tests that rely on many timers. In local testing, these
flags completely eliminated the problem.
IntensiveWakeUpThrottling is a web standard feature, and
TimerThrottlingForBackgroundTabs is a Blink-specific feature.

This updates the generator of experimental flags to only refer to one

Semantically the change does nothing, but it could make CLs that bump a

This splits ConstantVisitor(1) into a pure interface and a
ConstantVisitor(1)DefaultMixin with the base implementation. This is
a step towards avoid having an accidental default implementation where
a static error would have been preferable.
Also removes BodyVisitor1 which was unused.

There was a bug in source map generation introduced by this deferring. A map from JS Nodes to source map info is being shared between these two operations and in order to look up nodes in the map, the Node objects must be the same.
This gives up some but not all of the gains from deferring these function bodies. I'm working on a more long term fix that combines these two passes of the AST.

Before running CP find all branches of form `Branch(v eq C)`,
where `eq` is one of `===`, `==`, `!==` or `!=` and `C` is
a constant and insert a redefinition of `v` in the true
successor which captures the information that `v` is equal
to `C` guaranteed by the branch.
SCCP algorithm can then use this information when propagating
constants. After SCCP all redefinitions inserted are removed
again.
We don't actually replace `v` with `C` in the dominated code
because this might lead to issues later, for example
it might result in redundant phis `phi(C, v)` (`C` flowing
from a predecessor where `v == C`) which are complicated
to eliminate again.

This reverts commit 5a4b252252.
Reason for revert: Causing Flutter engine unit test failures, see https://github.com/dart-lang/sdk/issues/53506
Original change's description:
> [dart2wasm] Replace `struct.new_default` with `struct.new` for object
> allocation.
>
> When using the `struct.new_default` instruction for object allocation,
> fields are always nullable and mutable. By using the `struct.new`
> instruction instead, class fields can now have the same mutability and
> nullability in Wasm as declared in Dart. In addition, the class ID and
> type parameters (which are also stored in an object's struct), can now
> be immutable and nonnullable as well.
>
> To do this, object construction is now split into three functions:
> (1) Initializer: evaluates initializers for instance fields and
> constructor initializers (this constructor before super constructor).
> (2) Constructor body: executes the constructor body (super constructor
> before this constructor), with `this` pointed to the constructed object.
> (3) Constructor allocator: which calls (1), allocates the object using
> `struct.new`, then calls (2).
>
> Because fields now have the correct mutability and nullability in Wasm,
> this removes unnecessary null checks for nonnullable fields, and may
> allow for better optimisations by Binaryen.
>
> Fixes https://github.com/dart-lang/sdk/issues/51492

The `EfficientLengthIterable` is an internal marker interface
that allows the SDK to more efficiently check, effectively,
`v is List || v is Set || v is Queue`, and some other
known internal types, which allows it to assume that `.length`
is efficient and doesn't iterate the iterable.
It's not intended for external use, but the current design
both has the name mentioned specifically in the declaration
of the public types `List`, `Set` and `Queue`,
and possibly allows the type to leak through the
least-upper-bound algorithm.
This change moves the mention of `EfficientLengthIterable`
from the public types to an anonymously named private type,
and ensures that the private type is never the result of
a least-upper-bound computation, by adding another
interface with the same depth that all the public
types implementing `EfficientLengthIterable` also implement.
(A longer term solution to `EfficientLengthIterable` looking
like it's a public name could be combining the collection-
related code from `dart:collection`, `dart:core` and
`dart:_internal` into a single `dart:_collection_impl`,
and exporting the relevant types from there. Then
we could make the interface be `_EfficientLengthIterable`
again.)

`IsTrivial` is supposed to return true iff `ToCompileType` would
produce a trivial (dynamic) type. However `IsTrivial` was taking
some of the irrevant parts of the `InferredTypeMetadata` into
account - meaning that it returned `false` where it should have
returned `true`.
This lead us to assign useless `dynamic` result type to various `StaticCall`, some of these calls can later be lowered to
`LoadIndexed` instructions, which will then also get the `dynamic`
result type. This useless type will then take priority over more
precise element type which could be inferred by
`LoadIndexedInstr::ComputeType`
