All deserialized VarDecl initializers are EvaluatedStmt, but not all EvaluatedStmt initializers are from a PCH. Calling `VarDecl::hasInitWithSideEffects` can trigger constant evaluation, but it's hard to know ahead of time whether that will trigger deserialization - even if the initializer is fully deserialized, it may contain a call to a constructor whose body is not deserialized. By caching the result of `VarDecl::hasInitWithSideEffects` and populating that cache during deserialization we can guarantee that calling it won't trigger deserialization regardless of the state of the initializer. This also reduces memory usage by removing the `InitSideEffectVars` set in `ASTReader`. rdar://154717930
