Add mul_hi implementation [v2] Everything except long/ulong is handled by just casting to the next larger type, doing the math and then shifting/casting the result. For 64-bit types, we break the high/low parts of each operand apart, and do a FOIL-based multiplication. v2: Discard the stack-overflow implementation due to copyright concerns. - The implementation is still FOIL-based, but discards the previous code.
