// This is derived from a change to compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs, in
// preparation for adopting let-else within the compiler (thanks @est31):
//
// ```
// -    let place = if let mir::VarDebugInfoContents::Place(p) = var.value { p } else { continue };
// +    let mir::VarDebugInfoContents::Place(place) = var.value else { continue };
// ```
//
// The move was due to mir::Place being Copy, but mir::VarDebugInfoContents not being Copy.
