Auto merge of #79931 - RalfJung:no-redundant-storage-live, r=oli-obk
make redundant StorageLive UB

The interesting behavior of StorageLive in loops (https://github.com/rust-lang/rust/issues/42371) has been fixed, so we can now finally make it a hard error to mark a local as live that is already live. :)

r? `@oli-obk`
