When a signed integer is converted to an unsigned integer of the same size, the negative numbers cannot be represented in the target type. This is a form of overflow, and should throw an exception following the discussion in #796.

(Note: C treats "unsigned->signed" and "signed->unsigned" differently. "signed->unsigned" is always defined while "unsigned->signed" is sometimes undefined. I don't know the reason.)
