Also, do not try to use invokedynamic on SAM calls with intersection
types, because intersection type is not allowed as an immediate type
projection of a supertype, and constructing a fake override in
LambdaMetafactoryArgumentsBuilder led to an exception. This fixes the
problem which was worked around earlier in e6c089ef, effectively
reverting that commit.
The main motivation for this change is that LambdaMetafactory also
doesn't generate generic signature for SAM wrapper classes at runtime.
Since these classes are synthetic, nobody should rely on the fact that
they have generic supertypes, which was observable only via Java
reflection.

- Do not wrap exceptions resulting from generating error expressions
multiple times, as that could lead to stack traces where the identical
code is wrapped many times and is printed in the exception message on
each step, which was difficult to read
- Add element location (file name, line number & position) to the
message, similarly to exceptions from codegen, when catching and
rethrowing exceptions at the top level
The changes introduced 471134d31e are only needed
for the case of HMPP project while for other cases it might break the behavior
a bit like in KT-34027
See org.jetbrains.kotlin.resolve.calls.results.OverloadingConflictResolver#filterOutEquivalentCalls
Before 471134d we were comparing
"fun foo(x: String)" with "[substituted] fun foo(x: String)"
and areCallableDescriptorsEquivalent returned false for such case.
Thus, both overrides were left in the resulting set.
After 471134d, those two descriptors
becamed considered as equal thus having a possibility to remove any of them.
The problem is that "areCallableDescriptorsEquivalent" has kind of
unclear contract. Effectively it checks whether two descriptors match
to the same declaration
But straightforward fixing of this exact call-site (using original descriptors)
doesn't help: behavior might change in a very subtle way (see org.jetbrains.kotlin.spec.checkers.DiagnosticsTestSpecGenerated.NotLinked.Dfa.Pos#test72)
So, the main idea is changing the contract for areCallableDescriptorsEquivalent
only when project is HMPP one.
^KT-34027 In Progress
Move logic regarding expect classes to the only relevant call site at
PackageCodegenImpl, and return the list of members to remove code
duplication at remaining call sites
Make a separate subclass for DescriptorBasedFunctionHandle
to allow customize the behavior without complex abstract concepts
like `areDeclarationAndDefinitionSame`
- Give it more clear name mayBeUsedAsSuperImplementation
because defining if it can be used as super-implementation
this is what it used for
- The meaning is negated, so it's needed to negate its usages and impls
- Also, reuse it in findSuperImplementationForStubDelegation
It's difficult to fix KT-22818 until the IR comes along, so we're
providing a workaround where one can disable the
ACTUAL_FUNCTION_WITH_DEFAULT_ARGUMENTS error and provide default values
in the actual function, to avoid exception from the backend.
#KT-22818
This lead to an exception being thrown frequently
Proper fix would be to prevent binding context from being corrupted
Known cases are hard to debug/reproduce
#EA-101081 Fixed
After this change, optional expected annotations will be compiled to
physical class files on JVM, and stored to metadata on other platforms,
to allow their usages from dependent platform modules. For example:
@OptionalExpectation
expect annotation class A
When compiling this code on JVM, A.class will be produced as if the
class A did neither have the 'expect' modifier, nor had it been
annotated with OptionalExpectation. Note that if there's no actual
annotation class for A, then usages (which can only be usages as
annotation entries) are simply skipped.
Class A will be public from Kotlin's point of view (since it should
be possible to use it in Kotlin sources), but _package-private_ in Java
to disallow its usages outside of the declaring module.

In some cases when several bridge methods are generated, their order
is undetermenistic. For example for class ClassLowerWithContext in the
following example
```
interface IrElement
class IrClassContext
interface IrElementVisitor<out R, in D> {
fun visitElement(element: IrElement, data: D): R
}
interface IrElementTransformer<in D> : IrElementVisitor<IrElement, D> {
override fun visitElement(element: IrElement, data: D): IrElement =
element.also { throw RuntimeException() }
}
abstract class ClassLowerWithContext : IrElementTransformer<IrClassContext?>
```
kotlin compiler synthesizes two additional bridges:
public IrElement visitElement(IrElement, IrClassContext);
[bridge] public Object visitElement(IrElement, Object);
[bridge] public IrElement visitElement(IrElement, Object);
Unfortunately the behavior is not deterministic and not easy to reproduce.
Generate continuation type as kotlin.coroutines.Continuaion. This code will
fail at runtime since there is no stdlib backing this change yet.
However, in order to generate compatible stdlib we need a compiler, which
generates continuation type as kotlin.coroutines.Continuation.
Thus, firstly we support the change in the compiler, make it bootstrap
compiler and only then change stdlib and tests accordingly.

When plugins DSL is used, there is no need to
manually generate typesafe accessors for extensions and
conventions (by running `./gradlew kotlinDslAccessorsSnapshot`).
