R1 and R2 revisions), implements facilities required to emit those instructions
and provides LIT tests for added instructions.

This patch includes all missing functionality needed to provide first
compilation of a simple program that just returns from a function.
I've added a test case that checks for "ret" instruction printed in assembly
output.

This header includes CodeGen headers, and is not, itself, included by
any Target headers, so move it into CodeGen to match the layering of its
implementation.

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.
