In the past, if an
internaltypeTwas inferred to be stable when it was compiled in a compilation unitA, we would infer it to be stable when compiling a compilation unitBthat uses the type. This caused failures in situations in whichTwas later made unstable by an edit andAwas incrementally recompiled, butBwas not. This change eliminates the possibility of such failures.Test: ClassStabilityTransformTests.testInferredStabilityOfInternalTypesFromOtherCompilationUnits
