In case there are several proxy functions for indy lambdas in the same
container, its names are "...__proxy", "...__proxy-0", "...__proxy-1",
..., yet before this change, only the first one was sanitized. So if
it's happening inside a constructor, `<init>` was left unrenamed which
led to ClassFormatError.

We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
The JVM and newer Android runtimes treats that the same as if
there is no enclosing method. However, older Android runtimes
for Android 5 and 6 throw exceptions on reflective access
and even older runtimes have different behavior. To avoid
those issues, exclude <clinit> from enclosing method attributes.

val y = 1
object { val x = y }
->
class XKt$1(`$y`: Int) { val x: Int = `$y` }
Note that `$y` is not stored in a field because it's not used outside
the primary constructor.
One exception is captured inline parameters on the JVM backend, as the
bytecode inliner uses field assignment instructions (setfield) to locate
them; removing the field is thus not possible.
Generate $delegate method as instance method in
PropertyReferenceDelegationLowering, and remove dispatch receiver later
in MakePropertyDelegateMethodsStatic. The method needs to be static to
be non-overridable (see delegateMethodIsNonOverridable.kt), and public
to be accessible in reflection.
Otherwise we generated incorrect IR where a static function accessed an
instance field of the containing class, which failed in multiple places
including LocalDeclarationsLowering.
#KT-48350 Fixed
The problem in the test case was that `JImpl.entrySet` was detected by
ReplaceDefaultImplsOverriddenSymbols as a class fake override, which
overrides non-abstract interface method. Thus, overriddenSymbols of
`MyMap.entrySet` were changed in
`ReplaceDefaultImplsOverriddenSymbols.visitSimpleFunction`.
Later, BridgeLowering tried to determine which special bridges to
generate for `MyMap.<get-entries>`, and for that it inspected existing
methods and their overrides.
Normally we would generate the following special bridge:
getEntries()Ljava/util/Set;
invokespecial JImpl.entrySet()Ljava/util/Set;
However, because of incorrect overrides, the generated class method was
selected here instead of the expected `Map.<get-entries>`:
https://github.com/JetBrains/kotlin/blob/06001fc0919c814e757caa494891619882fae15f/compiler/ir/backend.jvm/src/org/jetbrains/kotlin/backend/jvm/lower/BridgeLowering.kt#L282
and since the JVM signature of the generated class method is the same as
that of the fake override in MyMap, we never got to generating the
special bridge.
The solution is to skip Java classes when looking for class methods
which override non-abstract interface methods. This logic only makes
sense for Kotlin code, because only Kotlin has DefaultImpls, and the
requirement to generate non-abstract fake overrides of interface methods
as actual methods in the bytecode, delegating to DefaultImpls.

Seperate checker for platforms that do not support this language feature yet
Synthetic implementations of annotations are generated on-demand with proper

Note that resulting SAM method
public final method accept(p0: java.lang.Object): void
has a signature less specific than the resulting bridge method
public synthetic bridge method accept(p0: X): void
