This puts the logic that selects which bits of the multiplier result get written into the destination GPR into execute1, moved out from multiply. The multiplier is now expected to do an unsigned multiplication of 64-bit operands, optionally negate the result, detect 32-bit or 64-bit signed overflow of the result, and return a full 128-bit result.
