Jack Carter 9c1a027fe8 This patch that sets the EmitAlias flag in td files 
and enables the instruction printer to print aliased 
instructions. 

Due to usage of RegisterOperands a change in common 
code (utils/TableGen/AsmWriterEmitter.cpp) is required 
to get the correct register value if it is a RegisterOperand.

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.
