Before #109999, this gave an error:
let f = format_args!("{}", "abc"); // error[E0716]: temporary value dropped while borrowed
dbg!(f);
But after #109999, that no longer gives an error.
Ideally it shouldn't give an error in any case, but that's a separate issue. Inlining/flattening format_args shouldn't change what compiles and what doesn't compile, so, for now, this still shouldn't compile.
