…t, r=oli-obk Pass correct place to `discriminant_switch_effect` PR rust-lang#69562, which fixed a bug that was causing clippy to ICE, mistakenly passed the place holding the *result* of `Rvalue::Discriminant` instead of the place holding its *operand* to `apply_discriminant_switch_effect` as the enum place. As a result, no effect was applied at all, and we lost the perf benefits from marking inactive enum variants as uninitialized. **edit:** The regression test has been split into rust-lang#69744. r? @oli-obk

Depends on #69676. This test should ensure that the problem fixed in that PR does not reoccur.
This has been split out from #69676 since the test fails on certain targets where no cleanup blocks are emitted. I have to find the correct
