If the wordsize is 64 bits, pack up to 4 operands into a word
In the 32-bit BEAM emulator, it is only possible to pack
3 register operands into one word. Therefore, the move2
instruction (that has 4 operands) needs two words for its
operands.
Take advantage of the larger wordsize in the 64-bit emulator
and pack up to 4 operands into a single word.
