Add missing `// run-pass` annotations to ICE tests compiletest UI tests do not fail when encountering panics and ICEs unless the `// run-pass` flag is used. (This was forgotten in https://github.com/rust-lang/rust-clippy/pull/3743)

// run-pass
fix cc computation in the presence of diverging calls CFG treats diverging calls as its completely own path out of the function. While this makes sense, it should also mean that a panic should increase the cyclomatic complexity. Instead it decreases it. Minimal example: ```rust if a { b } else { panic!("cake"); } d ``` creates the following graph ```dot digraph G { "if a" -> "b" "if a" -> "panic!(\"cake\")" "b" -> c } ``` which has a CC of 1 (3 - 4 + 2). A CC of 1 means there is one path through the program. Obviously that is wrong. There are two paths. One returning normally, and one panicking.

#[allow(dead_code)]
Move run-pass tests to UI tests This should give us more UI coverage for free. It also removes the `run-pass` suite, so we now only have the `ui` suite.
