[Interpreter] Optimize the Register Optimizer. Modify the Bytecode Register Optimizer to be an independent component rather than part of the BytecodePipeline. This means the BytecodeArrayBuilder can explicitly call it with register operands when outputting a bytecode and the Bytecode Register Optimizer doesn't need to work out which operands are register operands. This also means we don't need to build BytecodeNodes for Ldar / Star / Mov bytecodes unless they are actually emitted by the optimizer. This change also modifies the way the BytecodeArrayBuilder converts operands to make use of the OperandTypes specified in bytecodes.h. This avoids having to individually convert operands to their raw output value before calling Output(...).
