`mappedVarargElements` are populated with parameters from
`argumentMapping`, which is computed using `ArgumentsToParametersMapper`
which calls `original` on all value parameters (see
ArgumentsToParametersMapper.kt:136).
So the code that adds empty lists for unassigned vararg parameters
should also call `original`. Otherwise, in the added test, we ended up
with two arguments for the parameter `s` in `id(::base1)`, one for
`Base.s` containing the correct value, and another for `Derived.s`
containing the empty list. Psi2ir took the last one, which resulted in
empty array being passed to the vararg parameter.
Note that all of this is caused by the fact that `original` of a fake
override parameter is the parameter of the base function. This seems
suspicious because `original` of a fake override _function_ is that fake
override itself (NOT the base function), but this would probably be very
risky to change at this point.

Parameter of a synthetic SAM adapter always has a function type (not a
subtype). Checking for the subtypes broke the case from KT-46908, where
fun interface is itself a subtype of a function type.

In case the cast value is used as a receiver to a private method call,
the cast is actually necessary, see KT-48927. Also, this optimization
has backfired once already (see kt48659_identityEqualsWithCastToAny.kt).
It seems that the best way to optimize these casts is not to generate
them in the first place, and/or use bytecode postprocessing.
Apparently the only kind of casts which need to be eliminated are those
which occur on an inline class to its supertype. Otherwise the
unsafe-coerce intrinsic is inserted at the incorrect place, and several
tests fail (uncastInlineClassToAnyAndBack.kt, genericOverride.kt,
classGenericOverride.kt).
#KT-48927 Fixed
TL;DR, before we were emitting this JS code:
Object.defineProperty(Base.prototype, 'bar', {
configurable: true,
get: Base.prototype._get_bar__0_k$,
set: Base.prototype._set_bar__a4enbm_k$
});
Now we emit this code instead:
Object.defineProperty(Base.prototype, 'bar', {
configurable: true,
get: function () {
return this._get_bar__0_k$();
},
set: function (value) {
this._set_bar__a4enbm_k$(value);
}
});
This fixes the issue where if we had a @JsExport'ed base class with a
public property overridden in a non-exported derived class, we couldn't
access that property from JS if we were given an instance of
the derived class.

before checking whether they use the KProperty parameter. (Otherwise the
body is empty and the check always says that the parameter is unused.)

They may or may not be inlined later.
IDK how the test passes when both modules are compiled with the old
backend - perhaps this has something to do with the fact that when `f`
is compiled with the IR backend, the call to `x()` is followed by `pop`
and `getstatic kotlin/Unit.INSTANCE`? This is probably why the original
issue in kotlinx.coroutines reports that everything works fine with
kotlinx-coroutines-core:1.4.3.

- change test runner to production mode when sources are being compiled
into klib and then klib is being translated into js, not directly from
kt to js
- fix IC cache format
- support IC tests
While annotations restrict the set of allowed types to a few final
built-ins, in arbitrary constants we can have array elements that are
some subtype of the array's element type.

- Materialize unit when its value is actually needed.
- Special-case Unit_getInstance return type at codegen. It should be a
proper Unit object instead of a "void"
We can't apply "reuse loop variable as index variable" transformation
before local declarations lowering, otherwise it will affect captured
loop variable behavior, resulting in KT-48626.
Since it's JVM-specific, move it to JvmOptimizationLowering.
