It seems we can't quite bind object constructors yet. This doesn't make much sense, since they are just functions.

Fixed, apparently, long ago. Works now.

Contracts & Harnesses for unchecked_add (rust-lang#91)
1bf01fd 
Towards rust-lang#59 

* Added contracts for `unchecked_add` (located in
`library/core/src/num/int_macros.rs` and `uint_macros.rs`)
* Added a harness for `unchecked_add` of each integer type
* `i8`, `i16`, `i32`, `i64`, `i128`, `isize`, `u8`, `u16`, `u32`, `u64`,
`u128`, `usize` --- 12 harnesses in total.

Contracts and Harnesses for unchecked_neg (rust-lang#102)
32e0cf9 
Towards rust-lang#59 

### Changes
* Added contracts for `unchecked_neg` (located in
`library/core/src/num/int_macros.rs`)
* Added a harness for `unchecked_neg` of each signed integer type
  * `i8`, `i16`, `i32`, `i64`, `i128`, `isize` --- 6 harnesses in total.
* Fixed comments.

### Revalidation
1. Per the discussion in rust-lang#59, we have to **build and run Kani from
`feature/verify-rust-std` branch**.
2. To revalidate the verification results, run the following command.
`<harness_to_run>` can be either `num::verify` to run all harnesses or
`num::verify::<harness_name>` (e.g. `check_unchecked_neg_i8`) to run a
specific harness.
```
kani verify-std  "path/to/library" \
    --harness <harness_to_run> \
    -Z unstable-options \
    -Z function-contracts \
    -Z mem-predicates
```

All default harnesses should pass.

Contracts & Harnesses for wrapping_shl (rust-lang#112)
3a967e3 
Towards rust-lang#59 

### Changes
* Added contracts for `wrapping_shl` (located in
`library/core/src/num/int_macros.rs` and `uint_macros.rs`)
* Added a macro for generating wrapping_{shl, shr} harnesses
* Added harnesses for `wrapping_shl` of each integer type
* `i8`, `i16`, `i32`, `i64`, `i128`, `isize`, `u8`, `u16`, `u32`, `u64`,
`u128`, `usize` --- 12 harnesses in total.

### Revalidation
1. Per the discussion in rust-lang#59, we have to **build and run Kani from
`feature/verify-rust-std` branch**.
2. To revalidate the verification results, run the following command.
`<harness_to_run>` can be either `num::verify` to run all harnesses or
`num::verify::<harness_name>` (e.g. `checked_wrapping_shl_i8`) to run a
specific harness.
```
kani verify-std  "path/to/library" \
    --harness <harness_to_run> \
    -Z unstable-options \
    -Z function-contracts \
    -Z mem-predicates
```

All harnesses should pass the default checks (1251 checks where 1
unreachable).
```
SUMMARY:
 ** 0 of 1251 failed (1 unreachable)

VERIFICATION:- SUCCESSFUL
Verification Time: 2.4682913s

Complete - 1 successfully verified harnesses, 0 failures, 1 total.
```
Example of the unreachable check:
```
Check 123: num::<impl i8>::wrapping_shl.assertion.1
         - Status: UNREACHABLE
         - Description: "attempt to subtract with overflow"
         - Location: library/core/src/num/int_macros.rs:2172:42 in function num::<impl i8>::wrapping_shl
```

### Questions
1. Should we add `requires` (and `ensures`) for `wrapping_shl` given
that `unchecked_shl` already has a `requires`?
