Returns (a - b) mod 2N, where N is the width of T in bits.

Note that, unlike most intrinsics, this is safe to call; it does not require an `unsafe` block. Therefore, implementations must not require the user to uphold any safety invariants.

The stabilized versions of this intrinsic are available on the integer primitives via the `wrapping_sub` method. For example, `u32::wrapping_sub`
