Merge #387

387: Don't remove unreachable statements at HIR lowering r=philberty a=lrh2000

This is a legal code segment:
```rust
fn foo() -> i32 {
    return 1;
    let a = 1;
    a
}
```
And this is illegal:
```rust
fn foo() -> i32 {
    return 1;
    let a = 1.5;
    a
}
```
So we shouldn't remove unreachable statements at HIR lowering. We can issue warnings for them, but they need to be kept so that their types can be checked.
