I've also added some runtime checks to
`tests/language/patterns/object_pattern_inference_test.dart` to verify
that the object patterns match when they should match and don't match
when they shouldn't; this helps verify that not only has the front end
inferred the correct type for the object patterns, but it has also
stored the correct type in the kernel representation.
Fixes#51795.

This ensure that the StaticTypeContext used for 'evaluate' is only
used within the method call and doesn't leak to subsequent evaluations.
Included is a repro for the fix in
https://dart-review.googlesource.com/c/sdk/+/290860 which was triggered
by the same underlying problem of the leaky static type context

When unevaluated constants are found in conditions, a lazy region
is created for evaluating the subexpression, ensure that constant
locals are replaced within the subexpressions while still leaving the
subexpressions themselves unevaluated.
In these lazy regions, the result of evaluating the subexpressions
should not be cached, since these subexpressions are not themselves
unevaluated and should be evaluated if encountered elsewhere.
This was previously not done, leading to constants not being
evaluated even when these didn't contain any unevaluated constants.

Remove the special case for `class C = Object with M;`
and fall into the same code path that would be used for
`class C2 = BaseClass with M;`
This introduces one new class to the hierarchy but that
class contains the members synthesized on the class. This
ensures they do not get lost during the mixin application at
runtime.
It appears likely that this has been broken for some time and
generating incorrect code when methods require covariant checks.

`[...[...]]` instead of `[...]`. It is the plan to address this in

I'm reverting the work queue change for the main inferrer branch.

In the linearized algorithm the refinement limit is increased so I will keep it in that fork.

Today we track and constantly update maps of distinct callers throughout the inference algorithm. Instead we can simply iterate over all call sites and set the `isCalledOnce` flag after all call targets have settled. This result is not used in inference, it is just saved out to the results for the member so the timing doesn't matter.
On a large program this shows a ~4% memory improvement and marginal runtime improvements (in addition to 4% from https://dart-review.git.corp.google.com/c/sdk/+/290060/6).
