b365e657d4 Add unmeasurable variance kind for marking types whose variance result is unreliable (#30416) 
* Add unmeasurable variance kind for marking types whose variance result is unreliable

* Remove now-unneeded nongeneric checks

* Add rule allowing `Readonly<any>` to be `any` instead of `{readonly [index: string]: any}`

* All Unmeasurable variances to still shortcut structural comparisons in some cases

* Separate unmeasurable from unreliable to reduce the impact of this change, for now

* Fix lint

* Remove Readonly<any> -> any callout

* Add fix for circularity error triggered by deep signature return type comparisons with `this` types

f9d12ed54b fix 31012 allow noEmitOnError with isolatedModules (#34) (#31043) 
fix #31012

Since the purpose of isolatedModules: true is to
do extra validation to ensure that separate
compilation is safe

Allowing emit in the presence of errors is
compatible with that intention.

6487d1ffe0 Remove the rule that replaces a union of literal types with the base type when comparing equality to a type that isn't a union of literal types. (#27588) 
type when comparing equality to a type that isn't a union of literal
types.

The rule is redundant because a primitive type is already directed-
comparable to a value of that primitive type, and it causes errors to be
missed when comparing a type parameter _constrained_ by a union of
literal types to another union of literal types.

The baseline changes look like improvements to me.

Fixes #26758.
