JVM_IR: mark direct uses of inline lambdas as conditionally suspend

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.
