Do not compute optimized MIR if code does not type-check. Since https://github.com/rust-lang/rust/pull/128612, we compute optimized MIR when `-Zvalidate-mir` is present. This is done as part of required analyses, even if type-checking fails. This causes ICEs, as most of the mir-opt pipeline expects well-formed code.
