------------------------
The `i128_type` feature adds support for 128 bit signed and unsigned integer
types.
The `i128` feature adds support for `#[repr(u128)]` on `enum`s.
```rust
#![feature(i128_type)]
#![feature(i128)]
fn main() {
assert_eq!(1u128 + 1u128, 2u128);
assert_eq!(u128::min_value(), 0);
assert_eq!(u128::max_value(), 340282366920938463463374607431768211455);
assert_eq!(1i128 - 2i128, -1i128);
assert_eq!(i128::min_value(), -170141183460469231731687303715884105728);
assert_eq!(i128::max_value(), 170141183460469231731687303715884105727);
#[repr(u128)]
enum Foo {
Bar(u64),
