Rollup merge of rust-lang#140024 - cjgillot:continue-jumping, r=compiler-errors Remove early exits from JumpThreading. This removes early exits from rust-lang#131203 as I asked during review. The correctness of the backtracking is `mutated_statement` clearing all relevant conditions. If `process_statement` fails to insert a new condition, for instance by const-eval failure, `mutated_statement` still removes the obsolete conditions from the state. r? `@compiler-errors`
