[stdlib] Removing a few harmful overloads of <
[stdlib] Removing a few harmful overloads of <

At some point during the implementation of integer protocols these
overloads were necessary to make expressions like `i32 < 0` be faster
and unambiguous.
Now they are no longer necessary, and also cause problems for
expressions like `(u64 - u64) < u64`, where they cause the deprecated
`func - (Strideable, Strideable) -> Stride` be used, which is wrong, as
it will trap in many cases, where `func - (UInt64, UInt64) -> UInt64`
would not.
