When we've determined that we are going to invoke an erased inline class
method ('static foo-impl(this, ...)' in inline class), keep track of it
so that the remaining type mapping logic proceeds correctly.
#KT-26998 Fixed Target versions 1.3.20
When mapping callable method signature for erased inline class methods,
use original function descriptor instead of super declaration
(otherwise it would map to a default interface method with mismatching
signature).
When generating delegates to Kotlin default interface methods, keep
track of the original Kotlin types for delegating method arguments and
interface method arguments.
'original' for value parameters of fake overrides points to the
overridden function value parameters instead of the value parameter of
the unsubstituted function. This causes inconsistent type mapping for
inline classes implementing generic interfaces with default methods.

* The members of Result are isSuccess, isFailure, exceptionOrNull, getOrNull
* The rest of API is implemented via inline-only extensions
* There are two internal functions to hide detailed mechanics of an internal
Result.Failure class: createFailure and throwOnFailure
* Result.toString is explicit: either Success(v) or Failure(x)

<IMPL_SUFFIX> for method is a method signature hash,
if method value parameter types contain inline class types,
otherwise 'impl'.
Constructor methods are named as 'constructor-<IMPL_SUFFIX>'.
Synthesized 'box' and 'unbox' methods are named as
'<METHOD_NAME>-<IMPL_SUFFIX>'.
Erased implementations of overriding and non-overriding methods
are named as '<METHOD_NAME>-<IMPL_SUFFIX>'.
Fully specialized implementation of 'equals' will have a special suffix.
We might want to add 'init' blocks later, so now, for the sake of
binary compatibility with 1.3-RC binaries, we have to generate these
'constructor' calls.
Note that in some tests inline class boxing is no longer redundant,
because resulting value is passed to 'constructor' as an argument.
Avoid name clashes in cases such as
inline class Login(val login: String)
inline class Password(val password: String)
fun validate(login: Login) { ... }
fun validate(password: Password) { ... }
Same as for primitives: inline lambda expects to see a boxed value,
so, even if an argument is a local variable, it can't be remapped,
because it contains unboxed representation.
Arguments are put on stack in the direct order, and then stored into
local variables for inlining in the reversed order:
<arg0>
<arg1>
<arg2>
store <param2>
store <param1>
store <param0>
Original value parameter types were taken in direct order, though.
When we have a nullable inline class value with non-null underlying
type, corresponding value in unboxed representation is nullable. E.g.:
inline class Str(val value: String)
fun test(s: Str?) = listOf(s)
Here 'test(s: Str?)' accepts nullable 'java.lang.String' as a parameter.
When boxing/unboxing nullable values of such inline classes, take care
of nulls.
