This commit fixes an issue in the Partial Redundancy Elimination (PRE) optimization pass where address-space qualification was disregarded when handling COMPONENT_REF operations. By ensuring that the address-space context is correctly considered, this resolves a bug (PR60075) and ensures more accurate optimization. A new test case has been added to verify the fix.
