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.

be45f67454/src/asm/statements.rs (L897-L901)

To make the label name unique it's suffixed with the name of the current symbol.

r? ```@Amanieu```
