68b75033ad Split RawVec::grow up. 
The amortized case is much more common than the exact case, and it is
typically instantiated many times.

Also, we can put a chunk of the code into a function that isn't generic
over T, which reduces the amount of LLVM IR generated quite a lot,
improving compile times.

f420726566 Remove RawVec::double. 
It's only used once, for `VecDeque`, and can easily be replaced by
something else. The commit changes `grow_if_necessary` to `grow` to
avoid some small regressions caused by changed inlining.

The commit also removes `Strategy::Double`, and streamlines the
remaining variants of `Strategy`.

It's a compile time win on some benchmarks because the many
instantations of `RawVec::grow` are a little smaller.

6de6d70ae0 Modify SimplifyArmIdentity so it can trigger on mir-opt-level=1 
I also added test cases to make sure the optimization can fire on all of
these cases:

```rust
fn case_1(o: Option<u8>) -> Option<u8> {
  match o {
    Some(u) => Some(u),
    None => None,
  }
}

fn case2(r: Result<u8, i32>) -> Result<u8, i32> {
  match r {
    Ok(u) => Ok(u),
    Err(i) => Err(i),
  }
}

fn case3(r: Result<u8, i32>) -> Result<u8, i32> {
  let u = r?;
  Ok(u)
}

```

Without MIR inlining, this still does not completely optimize away the
`?` operator because the `Try::into_result()`, `From::from()` and
`Try::from_error()` calls still exist. This does move us a bit closer to
that goal though because:

- We can now run the pass on mir-opt-level=1

- We no longer depend on the copy propagation pass running which is
  unlikely to stabilize anytime soon.
