Summary:
These expressions already worked but weren't tested.

Summary:
- If only two registers are passed to a three-register operation, then the
first argument is both source and destination register.
- If a non-register is passed as the last argument, generate the immediate
version of the instruction.
Also mark DADD commutative and add scheduling information (to the generic
scheduler), and implement DSUB.

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.

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.
