Using f64's bit size probably wasn't actually *wrong*, but it would overshoot for no reason. This might have slowed down f32 parsing significantly.

The code there still triggers an ICE, but for different reasons (const eval unwraps the parse result).

Issue #31109 uncovered two semi-related problems: * A panic in `str::parse::<f64>` * A panic in `rustc::middle::const_eval::lit_to_const` where the result of float parsing was unwrapped. This series of commits fixes both issues and also drive-by-fixes some things I noticed while tracking down the parsing panic.
