This PR adds methods to unsigned integers to add signed integers with good overflow semantics under #![feature(mixed_integer_ops)].

The added API is:

// `uX` is `u8`, `u16`, `u32`, `u64`,`u128`, `usize`
impl uX {
    pub const fn checked_add_signed(self, iX) -> Option<Self>;
    pub const fn overflowing_add_signed(self, iX) -> (Self, bool);
    pub const fn saturating_add_signed(self, iX) -> Self;
    pub const fn wrapping_add_signed(self, iX) -> Self;
}


impl iX {
    pub const fn checked_add_unsigned(self, uX) -> Option<Self>;
    pub const fn overflowing_add_unsigned(self, uX) -> (Self, bool);
    pub const fn saturating_add_unsigned(self, uX) -> Self;
    pub const fn wrapping_add_unsigned(self, uX) -> Self;

    pub const fn checked_sub_unsigned(self, uX) -> Option<Self>;
    pub const fn overflowing_sub_unsigned(self, uX) -> (Self, bool);
    pub const fn saturating_sub_unsigned(self, uX) -> Self;
    pub const fn wrapping_sub_unsigned(self, uX) -> Self;
}

Maybe it would be interesting to also have add_signed that panics in debug and wraps in release ?

What are two (different from each other) use cases?

I've wanted both the checked and the wrapping versions of this many times.

Possibly-silly question: shouldn't there also be checked_add_unsigned? Seems like i32::MIN.checked_add_unsigned(u32::MAX) ought to work too, if there's the other-way-around one...

Yes, I think that it would be less useful but certainly more consistent. Also in this case we would need *_sub_signed too I think.

Fixed conflicts, added tracking issue, added signed with unsigned operations and renamed feature.
