  Log Message:
  -----------
  [libc][math] Implement full multiplication and quick_mul_hi for UInt class.

Implement full multiplication `UInt<A> * UInt<B> -> UInt<A + B>` and
`quick_mul_hi` that returns the higher half of the product `UInt<A> * UInt<A>`.
These 2 functions will be used for dyadic floating point class.
