Akira Hatanaka c7828356aa [mips] Print move instructions. 
"move $4, $5" is printed instead of "or $4, $5, $zero".

Akira Hatanaka f423672117 [mips] Use "or $r0, $r1, $zero" instead of "addu $r0, $zero, $r1" to copy 
physical register $r1 to $r0.

GNU disassembler recognizes an "or" instruction as a "move", and this change
makes the disassembled code easier to read.

Original patch by Reed Kotler.
