This fixes Java interop of inline functions, which use coroutines.
However, we cannot transform the state-machine. Thus, we generate
a $$forInline counterpart for suspend functions (similar to inline
suspend functions) and invokeSuspend$$forInline for lambdas if these
coroutines are going to transformed (i.e. are declared inside inline
functions).
During transformation we just skip method with state-machine and
transform the $$forInline counterpart. Of course, if inline site is
inline itself, we generate both state-machine version (which will be
dropped during the next transformation) and $$forInline version.
Consequently, the final version of the coroutines will not have
$$forInline counterpart.
Unfortunately, since CompileKotlinAgainstInlineKotlin tests do not allow
java sources, the tests for the interop are usual box tests.
