Use better error message for hard errors in CTFE Currently the same message is used for hard errors and soft errors. This makes hard errors use a message that indicates the reality of the situation correctly, since usage of the constant is never allowed when there was a hard error evaluating it. 2021-06-15 19:16:10 -04:00			`error[E0080]: evaluation of constant value failed`
Use #[track_caller] in const panic diagnostics. It was already used for the message. This also uses it for the spans used for the error and backtrace. 2021-07-09 15:21:58 +02:00			`--> $DIR/const-unwrap.rs:7:18`

Emit a hard error when a panic occurs during const-eval Previous, a panic during const evaluation would go through the `const_err` lint. This PR ensures that such a panic always causes compilation to fail. 2021-05-25 20:54:59 -05:00			For more information about this error, try `rustc --explain E0080`.
