Function std::intrinsics::ptr_offset_from

pub unsafe extern "rust-intrinsic" fn ptr_offset_from<T>(    ptr: *const T,     base: *const T) -> isize

???? This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

See documentation of <*const T>::offset_from for details.
