Earlier we always allowed to interpret `IrGetObjectValue` because
this value is used in const val getter. But now we do a special
check for such getter avoiding visit of `IrGetObjectValue` node.

This fixes an issue with checking for default values in call resolution
(see FirDefaultParametersResolver) where it is expected that the map
only contains a single compatible entry.
#KT-59613 Fixed
... as well as $SwitchMap and other synthetic classes generated by javac
or other JVM language compilers or runtimes.
Note that for Kotlin, all synthetic classes were already handled by the
subsequent check for `KotlinClassHeader.Kind.SYNTHETIC_CLASS`, but after
this change we won't call `ReflectKotlinClass.create` for those, which
is a minor optimization.
#KT-41373 Fixed
... for Kotlin-generated classes which do not correspond to a "class"
from the Kotlin language's point of view. For example, Kotlin lambdas,
file facade classes, multifile class facade/part classes, WhenMappings,
DefaultImpls. They can be distinguished from normal classes by the value
of `KotlinClassHeader.Kind` (which is the same as `Metadata.kind`).
Another theoretical option would be to throw exception at the point
where the `::class` expression is used, if the expression's type on the
left-hand side is a synthetic class. But we can't really do that since
it'll affect performance of most `<expression>::class` expressions.
So, construct a fake synthetic class instead, without any members except
equals/hashCode/toString, and without any non-trivial modifiers. It kind
of contradicts the general idea that kotlin-reflect presents anything
exactly the same as the compiler sees it, but arguably it's worth it to
avoid unexpected exceptions like in KT-41373.
In the newly added test, Java lambda check is muted but it should work
exactly the same as for Kotlin lambdas and other synthetic classes. It's
fixed in a subsequent commit.
#KT-41373 In Progress
Local classes and anonymous objects are normal classes and
kotlin-reflect can load all declarations and modifiers from them, and
support calling members, exactly in the same way as it does for normal
non-local classes.
#KT-41373 In Progress
kotlin-reflect works correctly already for Kotlin-generated local
classes and anonymous objects, but not for Java ones. This is fixed in a
subsequent commit.
#KT-41373 In Progress
Note that call-site class has no metadata for inlined local delegated
properties. Thus, for an inlined local delegated property we should
obtain declaration-site class as owner - otherwise, the corresponding
`PropertyReference` will have an owner without property metadata.
- Actualize muted K2 tests

infra had no respect for "// MODULE: ..." test directives
It basically can be replaced with IR interpreter. The only half-hack
was required in `PropertyReferenceLowering`. Const interpreter is
running before it, so we can't optimize some calls on const
properties that appear after this lowering. Solution is to inline
constants manually during property reference lowering.
Add some more filters on private/synthetic stuff (which doesn't matter
in practice) to make full and light analysis mode dumps as similar as
possible, so that all existing tests will pass for JVM IR. Unmute some
tests which were failing with the old JVM backend.
Tests on repeatable annotations are muted because in full analysis,
annotations are wrapped into the container (e.g. `@A(1) @A(2)` ->
`@A$Container(A(1), A(2))`), but they are no in the light analysis mode.
So there's always going to be a difference for these tests between full
and light analysis, unless we're going to change behavior of kapt, which
would be a kind of a breaking change.
#KT-58497 Fixed
To make these tests behave closer to kapt, since kapt is the primary use
case for the light analysis mode.
AbstractLightAnalysisModeTest compares the text dump of bytecode
obtained with full analysis and light analysis, removing things like
anonymous/synthetic entities. In the light analysis mode anonymous
objects in supertypes are always approximated, and in the full analysis
mode they are always present as is in signatures. So we're transforming
the text dump in the same way, by approximating anonymous objects in
signatures (more precisely, in return types of methods and fields) to
the supertype.
IR inliner should evaluate `apiVersionIsAtLeast` on compile-time (except
cases of inlining to inline functions from kotlin runtime) just as
bytecode inliner does.
^KT-59291: Fixed
Code in `ReplaceNumberToCharCallSitesLowering` relies on `Number.toChar`
being declared in IR as non-abstract. Otherwise the
`resolveFakeOverride` call there doesn't work, and the lowering can't
rewrite the call to `toInt().toChar()`, and we end up with a call to the
missing method `Number.toChar` in the bytecode.
#KT-57217 Fixed
Function `apiVersionIsAtLeast` was introduced to be able to have
different inline function content inlined to user code call sites
depending on their api version settings. Thus, it should not be
compile-time evaluated when being called in the body of inline stdlib
function.
