Auto merge of #79653 - tmiasko:naked-functions, r=Amanieu
Validate naked functions definitions Validate that naked functions are defined in terms of a single inline assembly block that uses only `const` and `sym` operands and has `noreturn` option. Implemented as future incompatibility lint with intention to migrate it into hard error. When it becomes a hard error it will ensure that naked functions are either unsafe or contain an unsafe block around the inline assembly. It will guarantee that naked functions do not reference functions parameters (obsoleting part of existing checks from #79411). It will limit the definitions of naked functions to what can be reliably supported. It will also reject naked functions implemented using legacy LLVM style assembly since it cannot satisfy those conditions. https://github.com/rust-lang/rfcs/pull/2774 https://github.com/rust-lang/rfcs/pull/2972
