Implementations on Foreign Types

Gets the Integer type from an attr::IntType.

Finds the appropriate Integer type and signedness for the given signed discriminant range and #[repr] attribute. N.B.: u128 values above i128::MAX will be treated as signed, but that shouldn’t affect anything, other than maybe debuginfo.
