General rule to use linkedLabel or linkWithLabel
when label from node is reused in other instructions.
If label is not linked then it will point to another labelNode when visited

Actually we do need to generate delegates to DefaultImpls even for Java
SAM wrappers, so this condition is incorrect. However, this never worked
properly anyway because of KT-12466.
Don't mangled functions annotated with @JvmName.
Annotate 'Result.success' and 'Result.failure' with @JvmName and
@Suppress("INAPPLICABLE_JVM_NAME").
NB this would require bootstrap.
A mechanism that allows kotlinx.serialization plugin to preserve the
correct (program) order of properties after serializing/deserializing
descriptors to kotlin metadata, which is needed for correct and stable
json serialization of class hierarchies in incremental/multi-module scenario.
It uses protobuf extensions.
There are multiple ways to declare a named variable-like entity in
Kotlin:
1. val/var variable declaration
2. destructuring declaration
3. parameter of a function
4. parameter of a lambda
5. destructured lambda parameter
6. for-loop's variable declaration
7. catch block exception declaration
8. val in when
9. field declaration
Out of them, only variable and field can be assignable, in other words,
they can be on the left hand side of an assignment.
Val/var variable declarations were already supported.
So, we needed to just support field initialization and tell the backend
that other ways are prohibited. Function and lambda parameters were
already been supported. So, the only thing to explain to the backend are
remaining ways.

Since 1.4.0-dev-8774, we mangle functions returning inline class values,
including functions with return type 'kotlin.Result'. This causes
incompatibility when 1.4 compiler is used with 1.3 (or just some
pre-1.4.0-dev-8774) standard library.
Also, write "message from the future" on functions returning inline
class values indicating that they can be used since compiler version 1.4
(otherwise 1.3 compiler using 1.4 stdlib would fail to find some
@InlineOnly functions such as 'Result.success' and 'Result.failure').
When we generate call for 'foo', we make decision about invoking
a 'foo$default' too late, after the call arguments are generated.
If 'foo' was an override, and base class (interface) was generic,
'foo' in base class could have a different Kotlin and JVM
signature, so the arguments we generated could be generated wrong
(primitive or inline class values instead of boxes, see KT-38680).
Also, we always selected first base class in supertypes list,
which caused KT-15971.
Look into resolved call and see if we should actually call
'foo$default' instead of 'foo' when determining actual callable.
Overrides can't introduce default parameter values, and
override-equivalent inherited methods with default parameters
is an error in a child class. Thus, if we are calling a class
member function with a default parameters, there should be one
and only one overridden function that has default parameter values
and overrides nothing.
A follow-up for KT-35006:
fun f() = foo {
bar()
}
inline fun foo(crossinline x: () -> Unit) = { x() }()
inline fun bar() = TODO()
does not provide the option to navigate to bar's call site at all.
* a writing source mapper has `mapLineNumber(line, file, class)` that
inserts a new SMAP entry and returns a fake line number from it;
* a copying source mapper has `mapLineNumber(line)` that uses an
existing SMAP to resolve the line number and call the former method
on a different source mapper;
* those two types are disjoint.
