[jdk21u] RFR: 8312440: assert(cast != nullptr) failed: must have added a cast to pin the node

I backport this for parity with 17.0.10-oracle.

After it being backported to 17.0.10-oracle,
the risk of bringing it to 21 should be acceptable as this will have much less exposure.

Test passes on top of 8308103. Will run it through SAPs testing.
