Nikolai Bozhenov be4aef480e [Nios2] Subtarget, basic infrastructure for frame, instructions and registers
This is the second minimal patch keeping Nios2 target buildable.
I'm adding subtarget here and other stuff for frame lowering, instruction,
register information methods. I do not add any test cases, as still there
are missing parts like DAG selector and assembly printing. I plan to include
them into the next patch.
