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. Patch by Andrei Grischenko <andrei.l.grischenko@intel.com> Differential Revision: https://reviews.llvm.org/D37256 llvm-svn: 313626
