Use code generation attributes to ensure that naked functions are never inline, replacing separate checks in MIR inliner and LLVM code generation.

but actually NO_COVERAGE is no longer a thing in the compiler. Sadly, the link to the issue is broken, so I don't know what the problem was originally, but I don't think this is relevant any more with the global asm approach
