Add FileCheck annotations to mir-opt/dest-prop tests Part of https://github.com/rust-lang/rust/issues/116971, adds FileCheck annotations to MIR-opt tests in tests/mir-opt/dest-prop. I would like some feedback. Also, I don't know how to approach `union.rs`. I couldn't figure out what it is testing. r? cjgillot
