Set hidden visibility on naked functions in compiler-builtins
88b46460fa made builtin functions hidden, but it doesn't apply to naked functions, which are generated through a different code path.
This was discovered in rust-lang/rust#151486 where aarch64 outline atomics showed up in shared objects, overriding the symbols from compiler-rt.
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
