RFR: JDK-8318176: C2: dont assert in ~GraphKit if compilation had been interrupted

[Thomas Stuefe]

If compilation had been interrupted, which may have happened e.g. due to reaching the node limit check, the using code may not have called `GraphKit::transfer_exceptions_into_jvms()` yet; in that case, we should not assert.
