Stop making any assumption about the projections applied to the upvars in the `ByMoveBody` pass So it turns out that because of subtle optimizations like [`truncate_capture_for_optimization`](https://github.com/rust-lang/rust/blob/ab5bda1aa70f707014e2e691e43bc37a8819252a/compiler/rustc_hir_typeck/src/upvar.rs#L2351), we simply cannot make any assumptions about the shape of the projections applied to the upvar locals in a coroutine body. So stop doing that -- the code is resilient to such projections, so the assertion really existed only to "protect against the unknown". r? oli-obk Fixes #123650
