This PR uses the inline error suggestions introduced in #24242 to modify a few existing `help` messages. The new errors look like this: foobar.rs:5:12: 5:25 error: expected a path on the left-hand side of `+`, not `&'static Copy` [E0178] foobar.rs:5 let x: &'static Copy + 'static; ^~~~~~~~~~~~~ foobar.rs:5:12: 5:35 help: try adding parentheses (per RFC 438): foobar.rs: let x: &'static (Copy + 'static); foobar.rs:2:13: 2:23 error: cast to unsized type: `&_` as `core::marker::Copy` foobar.rs:2 let x = &1 as Copy; ^~~~~~~~~~ foobar.rs:2:19: 2:23 help: try casting to a reference instead: foobar.rs: let x = &1 as &Copy; foobar.rs:7:24: 7:25 error: expected expression, found `;` foobar.rs:7 let x = box (1 + 1); ^ foobar.rs:7:13: 7:16 help: try using `box()` instead: foobar.rs: let x = box() (1 + 1); This also modifies compiletest to give the ability to directly test suggestions given by error messages.
