The main change here is in `JvmInlineClassLowering.visitFunctionAccess`, where we now store the substituted return type of the function as the type of the call expression. Without it, the call could have a meaningless type, e.g. some `T` which is inaccessible at that place, and that could backfire in subsequent lowerings in codegen. For example, in the `stringPlus.kt` test, it would prevent the code in `FlattenStringConcatenationLowering.isStringPlusCall` from recognizing and replacing the `String.plus` call, leading to a codegen exception. Other changes are mostly cosmetics to make the code similar to `visitFunctionReference`, and preventive optimizations for the case when the substitution map is empty.
