According to KT-21354, this should be a warning in 1.2 and before, and
no warning (with changed semantics) in 1.3 and later.
NB there are some false positives in this check.

On JVM, strip @EnhancedNullability annotation from inferred types for
functions, properties, and local variables, so that these annotations
do not "escape" from Kotlin declarations.
If an expression with type annotated with @EnhancedNullability is used
as a function expression body, or property initializer, or variable
initializer, and corresponding type can not contain null,
generate nullability assertions for this expression.
Effectively, this commit drops cached value for j.l.Object type
This cache was introduced when types were immutable, but they
became mutable after starting reading top-level TYPE_USE annotations,
that lead to changing shared JAVA_LANG_OBJECT_CLASSIFIER_TYPE instance
#KT-20826 Fixed
Constant expressions are inlined if they do not depend on non-inlineable
vals.
Java constants are always inlined.
Kotlin constants are inlined in LV 1.1+.
- Introduce new definitions in descriptors.proto
- Add new corresponding values in Flags.java
- Introduce ContractSerializer and ContractDeserializer, responsible for
for conversion ContractDescription <-> ProtoBuf.Contract
- Add dependency of 'serialization' module on 'resolution' so that it
could see contracts model.
Note that here we do a lot of seemingly unnecessary hoops, which in fact
necessary to respect existing module system (in particular, to be able
to extract ContractDescription declarations from 'descriptors' module to
make them invisible from reflection)

Effect System introduction: 8/18
Three modes:
- 'disable' (default): normalize constructor calls in coroutines only
(required because uninitialized objects can't be stored in fields),
don't insert additional code for forced class initialization;
- 'enable': normalize constructor calls,
don't insert additional code for forced class initialization;
- 'preserve-class-initialization': normalize constructor calls,
insert additional code for forced class initialization.
In case of partial/incremental compilation, a module usually consists of
two roots, one of which is source and another is binary. Thus, it's
incorrect to divide modules into "binary" and "non-binary", and only
look for .class files in "binary" modules in
CliJavaModuleResolver.findJavaModule. The more correct way is to think
of a module as a collection of roots, and every root is either binary or
source
Only top-level types on fields, methods' return types and
value parameters are supported to catch-up how class-files are loaded
in IntelliJ (see IDEA-153093)

- do not allow it to be used together with JvmMultifileClass (otherwise
implementation becomes complex)
- do not allow to declare classes in a JvmPackageName-annotated file
(similarly, the implementation of this would be much harder in the
compiler, and there would need to be special support in the IDE)
- check that the value is a valid FQ name
- do not allow root package just in case
The main changes are in jvm_package_table.proto and ModuleMapping.kt.
With JvmPackageName, package parts can now have a JVM package name that
differs from their Kotlin name. So, in addition to the old package parts
which were stored as short names + short name of multifile facade (we
can't change this because of compatibility with old compilers), we now
store separately those package parts, which have a different JVM package
name. The format is optimized to avoid storing any package name more
than once as a string.
Another notable change is in KotlinCliJavaFileManagerImpl, where we now
load .kotlin_module files when determining whether or not a package
exists. Before this change, no PsiPackage (and thus, no JavaPackage and
eventually, no LazyJavaPackageFragment) was created unless there was at
least one file in the corresponding directory. Now we also create
packages if they are "mapped" to other JVM packages, i.e. if all package
parts in them have been annotated with JvmPackageName.
Most of the other changes are refactorings to allow internal names of
package parts/multifile classes where previously there were only short
names.
This annotation is currently internal because we only commit to its
support for our own libraries. It will be used to change JVM package
names of declarations in JDK-specific stdlib additions (now called
kotlin-stdlib-jre7/8), both to preserve source compatibility of the old
Kotlin code and to solve the split package problem (KT-19258)
Search abstract members in unsubstituted scope to avoid computation
of substituted descriptors for each type (effectively for each SAM call)

It might be helpful for performance as these methods are called
for each resolution candidate and in the same time they scan
the whole overridden tree of a callable member
- Tell user what exactly is not supported (e.g., local inline function)
- Reduce diagnostics range to a keyword or an identifier
where appropriate
#KT-16223 Fixed Target versions 1.1.50
In Kotlin 1.1 and before, there were no nullability assertions on
extension receivers, because receiver is resolved with NO_EXPECTED_TYPE.
So, if an expression of platform type is passed as an extension receiver
to a non-private function, it would fail with IllegalArgumentException.
However, if the function is private, then we generated no parameter
assertions under assumption that such function can be called from Kotlin
only, and all arguments are checked on the call site. Thus 'null' could
propagate indefinitely.
In Kotlin 1.2, we do the following:
- Generate nullability assertions for expression receivers.
NB nullability assertions are stored for ReceiverValue instances, not
for expressions: given expression can act as receiver in different
calls, each with an expected receiver type of its own.
- Generate nullability assertions for extension receivers of private
operator functions.
NB it still can throw NPE for some particular "optimized" cases, but at
least those nulls would not propagate indefinitely.
This behavior is disabled by an "advanced" command-line option
'-Xno-receiver-assertions'.
Rename addDeclarations -> registerModuleComponents
Use it to provide SamWithReceiverResolver extensions instead
Post construction on container composition can be achieved
but manually inserting injections where it seems appropriate
is bug prone
This fixes a bug where SamWithReceiverPlugin extension was not registered
for some containers in IDE which led to incorrect highlighting in IDE
Add IDE test for applying SamWithReceiver plugin
