Box/unbox nullable inline class values with null check

Browse Source 
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.
