Original problem is that lowered ir closures doesn't meet inliner expectations
about captured variable position in inlining method.
E.g.: Call 'foo(valueParam) { capturedParam }' to
inline function 'foo' with declaration
inline fun foo(valueParam: Foo, inlineParamWithCaptured: Bar.() ->) ....
is reorganized through inlining to equivalent call foo(valueParam, capturedParam1, cp2 ...).
But lowered closure for lambda parameter has totally different parameters order:
fun loweredLambda$x(extensionReceiver, captured1, cp2..., valueParam1, vp2...)
So before inlining lowered closure should be transformed to
fun loweredLambda$x(extensionReceiver, valueParam1, vp2..., captured1, cp2..)
#KT-28547 Fixed
Most of these tests used this directive as a way to opt in to a new
language feature, and most of those features are already stable for a
long time, so no opt-in is needed. Some other tests used the directive
to opt out from a language feature, replace those by the `LANGUAGE`
directive. One test used the directive to test behavior that actually
depended on the API version; use `API_VERSION` directive there instead.
Instead of trying to access a missing field `Foo.foo`, call the
synthetic accessor `Foo.access$getFoo$cp` which, as per previous commit,
no longer contains the lateinit assertion
#KT-21862 Fixed
Previously, for a property named `x` in the companion object of a class
named `Foo`, we generated:
- `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x` and lateinit
assertion
- `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp`
Now, we generate:
- `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x`
- `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp`
and lateinit assertion
The reason is that this way we can avoid generating another accessor and
reuse `Foo.access$getX$cp` in case `isInitialized` is called on a
lateinit property from companion.
For private properties, getX is not generated, but instead the assertion
is generated on each access to the field (which can be improved, see
KT-28331). The same happens for access to non-private properties from
inside the same context where they're declared.
#KT-21862 In Progress
Local lateinit var differs in behavior from a simple local var,
and logic that relies of 'instanceof Local' checks assuming that all
instances of Local are simple local vars can produce faulty code
(as in KT-23260, where a local lateinit var was not explicitly put on
stack when passed as an argument to an inline function, thus causing
null propagation).
#KT-23260 Fixed Target versions 1.2.50
Before this change, we were computing the visibility of an inherited
private property setter, and ISE at AsmUtil.getVisibilityAccessFlag
happened ("invisible_fake is not a valid visibility in backend")
Use it for char boxing/unboxing and unit materialization.
Possible to use for other purposes, for example, to add type checks
to dynamics.

When a test is marked as ignored in JVM BE (i.e. IGNORE_BACKEND: JVM)
it's ignored in LightAnalysisModeTestGenerated. This means that
this tests is expected to fail. However, often tests that fail
in JVM blackbox tests, don't fail in LAMTG, therefore it's reasonable
to skip these tests in LAMTG at all.
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
