It's not necessary (because these types are already set correctly by
the summary linker) and it causes incorrect behavior (because due to
issue #34579 the AST nodes don't always contain correct types).
This reduces the severity of #34579 by ensuring that the incorrect
types stay in the AST nodes and don't leak into the element model.
I'll leave that issue open to remind us to make a more complete fix.

I'd like to land this for now, but I probably will reintroduce it a
bit later. The problem is that this again the same problem with
handles, and I don't want to make it into internal build as is.

Since this method is only used to find supertype constraints that are
relevant for mixin inference, it can save its caller from doing extra
work by filtering out mixins that don't take type parameters.
Previously, we were doing that when supporting the old "--supermixin"
feature, but not when using the new mixin syntax.
The method has been renamed to
gatherMixinSupertypeConstraintsForInference so that it's less
surprising that it doesn't return *all* supertype constraints.

In a named mixin application, the superclass doesn't include the last
type appearing in the "with" clause, so that class isn't considered a
superclass constraint.

Now that we have an explicit syntax for mixins that is available all
the time, we have to do mixin inference error checking all the time,
not just when the "--supermixin" flag is supplied.
This required fixing several minor bugs:
- ErrorVerifier._checkForMixinSuperInvokedMembers did not properly
handle a mixinElement argument that was a ClassElementHandle.
- ErrorVerifier._checkMixinInference wasn't using the actual
substituted mixin types, causing errors to be wrongly reported when
a class declaration had multiple inferred mixins (this was the root
cause of #34404).
- Type names in "with" clauses in the resolved AST weren't properly
reflecting the mixin type arguments that had been inferred.
Fixes#34404.

So, instead of iterating over all subtypes and checking their supertypes
in string lists, we encode the supertype string id into int once, and
search for it in the denormalized supertype list.
This helps for files with really many classes and subtypes, such as
element.dart and as.dart (both interfaces, not implementations).

This improves performance of computing 'implemented' notifcations in
large workspaces (about 3000 files in the performance data below) and
multiple classes in the target file.
Here is data for switching between a file with a few classes, and file
with many classes. With this change it works about 10 times faster.

Fixes#34167. This implements the Dart 2 mixin proposal
(https://goo.gl/KEKQyv) for DDC. When the mixin is applied, a class
is created for the application that extends the correct superclass
and has all of the instance members, so `super` works correctly.
This also fixes a few minor issues in Analyzer's (mostly complete)
implementation:
- InterfaceType.isObject now returns false for Dart 2 mixins.
- Least upper bound calculation recognizes mixins are not Object.
- Interface of the mixin now implements its superclass constraints.
- Mixin superclass constraints are checked against the superclass and
all previously applied mixins (if any); this keeps it working with
the subtype fix above, and also prevents a not-yet-applied mixin
from satisfying the constraint
The language_2/mixin_declaration tests were updated with a few minor
fixes now that we can run Analyzer/dartdevc to test them.
This change implements super mixins for DDC's Kernel backend (DDK)
too. This will be enabled once Kernel adds a flag to recognize which
Class nodes are mixins (vs normal classes).

Before this change we used the whole AnalysisOptions.signature as salt.
This means that if two packages have different set of lints, they have
different options signatures, and so we have to parse and compute
unlinked data for SDK and all shared packages separately. But unlinked
data depends only on very small set of options, practically only on
parser options.
This improves performance on workspaces with many modules and empty
cache:
Before:
<= --- Analyzing in 36122 ms.
<= Computed implemented in: 50138 ms.
<= --- Analyzing in 47905 ms.
<= Computed implemented in: 55339 ms.
<= --- Analyzing in 45141 ms.
<= Computed implemented in: 60169 ms.
After:
<= --- Analyzing in 27957 ms.
<= Computed implemented in: 11645 ms.
<= --- Analyzing in 21378 ms.
<= Computed implemented in: 9439 ms.
<= --- Analyzing in 21719 ms.
<= Computed implemented in: 10546 ms.
Here "computed implemented" is computing subtypes of classes in the
open file - it required unlinked data for all files in all available
packages.
It also helps for full cache:
analysis: 6300 vs. 5700 ms.
implemented: 5700 vs. 3700 ms.

When this flag is enabled, we fail:
2 language_2/ tests;
25 Analyzer tests (mostly by 2 reasons);
0 Analysis Server tests.
There is a know problem: because unlinked summaries don't include
initializers for variables, we fail to recognize API changes related
to inferred types. I will fix this be computing API signatures from
pertinent tokens.
