The Mips standalone assembler aliased instruction support.
The assembler can alias one instruction into another based
on the operands. For example the jump instruction "J" takes
and immediate operand, but if the operand is a register the
assembler will change it into a jump register "JR" instruction.
These changes are in the instruction td file.
