x86_emulate: MOVSXD must read source operand just once

... for the case of accessing MMIO.

Also streamline the ARPL emulation a little, and add tests for both
instructions (the MOVSXD one requires a few other adjustments, as we
now need to run in a mode where the emulator's mode_64bit() returns
true).
