Rollup merge of #146793 - folkertdev:naked-asm-func-end, r=Amanieu
naked_asm: emit a label starting with `func_end` The `cargo asm` tool (`cargo install cargo-show-asm`) pattern matches on such labels to figure out where functions end: normal functions generated by LLVM always do have such a label. We don't guarantee that naked functions emit such a label, but having `cargo asm` work is convenient. https://github.com/pacak/cargo-show-asm/blob/be45f67454ad8b634246a7fc69b3c6a963ee93f1/src/asm/statements.rs#L897-L901 To make the label name unique it's suffixed with the name of the current symbol. r? ```@Amanieu```
