Mikhail Glukhikh 9c1551bca9 Implementation of smart casts for public / protected immutable properties that are not open and used in the same module.
DataFlowValueFactory and its environment refactoring: containing declaration is added into factory functions
as an argument and used to determine identifier stability. A few minor fixes. #KT-5907 Fixed. #KT-4450 Fixed. #KT-4409 Fixed.

New tests for KT-4409, KT-4450, KT-5907 (public and protected value properties used from the same module or not,
open properties, variable properties, delegated properties, properties with non-default getter).
Public val test and KT-362 test changed accordingly.

Several directives can be added in the beginning of a test file in the syntax:

// !DIRECTIVE

Directives:

1. DIAGNOSTICS

Must be

'([ + - ! ] DIAGNOSTIC_FACTORY_NAME | ERROR | WARNING | INFO ) +'

where

  • '+' means 'include';

  • '-' means 'exclude';

  • '!' means 'exclude everything but this'.

    Directives are applied in the order of appearance, i.e. !FOO +BAR means include only FOO and BAR.

Examples:

// !DIAGNOSTICS: -WARNING +CAST_NEVER_SUCCEEDS

// !DIAGNOSTICS: -UNUSED_EXPRESSION -UNUSED_PARAMETER -UNUSED_VARIABLE

2. CHECK_TYPE

The directive adds the following declarations to the file:

class _<T>
fun <T> T.checkType(f: (_<T>) -> Unit) = f

With that, an exact type of an expression can be checked in the following way:

fun test(expr: A) {
   expr checkType { it: _<A> }
}

Usage:

// !CHECK_TYPE

3. FILE

The directive let you compose a test consisting of several files in one actual file.

Usage:

// FILE: A.java /* Java code */

// FILE: B.kt /* kotlin code */
