Rollup merge of #143293 - folkertdev:naked-function-kcfi, r=compiler-errors
fix `-Zsanitizer=kcfi` on `#[naked]` functions fixes https://github.com/rust-lang/rust/issues/143266 With `-Zsanitizer=kcfi`, indirect calls happen via generated intermediate shim that forwards the call. The generated shim preserves the attributes of the original, including `#[unsafe(naked)]`. The shim is not a naked function though, and violates its invariants (like having a body that consists of a single `naked_asm!` call). My fix here is to match on the `InstanceKind`, and only use `codegen_naked_asm` when the instance is not a `ReifyShim`. That does beg the question whether there are other `InstanceKind`s that could come up. As far as I can tell the answer is no: calling via `dyn` seems to work find, and `#[track_caller]` is disallowed in combination with `#[naked]`. r? codegen ````@rustbot```` label +A-naked cc ````@maurer```` ````@rcvalle````
