Rollup merge of #48432 - flip1995:lit_diag, r=oli-obk
Suggest type for overflowing bin/hex-literals Fixes #48073 For hexadecimal and binary literals, which overflow, it gives an additional note to the warning message, like in this [comment](https://github.com/rust-lang/rust/issues/48073#issuecomment-365370113). Additionally it will suggest a type (`X < Y`): - `iX`: if literal fits in `uX` => `uX`, else => `iY` - `-iX` => `iY` - `uX` => `uY` Exceptions: `isize`, `usize`. I don't think you can make a good suggestion here. The programmer has to figure it out on it's own in this case. r? @oli-obk
