This patch removes alias definition for addiu $rs,$imm
and instead uses the TwoOperandAliasConstraint field in
the ArithLogicI instruction class.
This way all instructions that inherit ArithLogicI class
have the same macro defined.
The usage examples are added to test files.

This patch adds alias for addiu instruction which enables following syntax:
addiu $rs,imm
The macro is translated as:
addiu $rs,$rs,imm

Mips assembler supports macros that allows the OR instruction
to have an immediate parameter. This patch adds an instruction
alias that converts this macro into a Mips ORI instruction.

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.

but I cannot reproduce the problem and have scrubed my sources and
even tested with llvm-lit -v --vg.
The Mips RDHWR (Read Hardware Register) instruction was not
tested for assembler or dissassembler consumption. This patch
adds that functionality.

register names in the standalone assembler llvm-mc.
Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.
The problem is resolved by the Mips specific AsmParser
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.

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.
Test cases included
