Out-of-range float literals are not checked by type-limits lint

[huonw]

e.g.

fn main() { println!("{} {}", 1e310, 1e-360 == 0.0); } // prints `inf true`.

I worked on this but unforunately rust's from_str_bytes_common which I have to use for parsing the string representation of ast::LitFloat fails parsing f32::MAX_VALUE and friends.
See #14353 for the issue.

Closed by #14519, thanks @hirschenberger!
