8269746: C2: assert(!in->is_CFG()) failed: CFG Node with no controlling input?

[RealLucy]

This backport is for parity with 11.0.20-oracle.
The patch did not apply cleanly. The "before version" of the modified code block did not differ, though.

Tests (GHA and SAP-internal) were successful.

Reviews are welcome!
