Alexander Udalov e079fb665e JVM IR: fix inheritance from mutable collections of Int

For subclasses of `AbstractMutableList<Int>` which are not inline
classes, the special bridge `remove` had a parameter of type `Int`
(mapped to JVM primitive int) before this fix. The hack in
`MethodSignatureMapper` changed this type to `Int?`, yet the body of the
special bridge still loaded it as non-nullable, which resulted in
incorrect bytecode.

It looks like a part of this hack in `BridgeLowering` was made only for
inline classes which are subclasses of mutable collections. Supposedly
it should be extended to non-inline classes, so that `remove` special
bridge would have consistent IR by the time it reaches codegen.
