Merge #390

390: Clean up the compilation of block expressions r=philberty a=lrh2000

The original implementation of compiling block expressions and function bodies is incorrect. Here is an example.
```rust
fn foo() -> i32 {
    1;
    2;
    0
}
```
The above Rust code will compile into the below GIMPLE code.
```c
i32 foo ()
{
  i32 D.199;

  D.199 = 1;
  return D.199;
  D.199 = 2;
  return D.199;
  D.199 = 0;
  return D.199;
}
```
It is obviously incorrect.
