Nikolai Bozhenov 1cf9c54e5c [Nios2] final infrastructure to provide compilation of a return from a function 
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.

Matthias Braun bb8507e63c Revert "TargetMachine: Merge TargetMachine and LLVMTargetMachine" 
Reverting to investigate layering effects of MCJIT not linking
libCodeGen but using TargetMachine::getNameWithPrefix() breaking the
lldb bots.

This reverts commit r315633.

Matthias Braun 3a9c114b24 TargetMachine: Merge TargetMachine and LLVMTargetMachine 
Merge LLVMTargetMachine into TargetMachine.

- There is no in-tree target anymore that just implements TargetMachine
  but not LLVMTargetMachine.
- It should still be possible to stub out all the various functions in
  case a target does not want to use lib/CodeGen
- This simplifies the code and avoids methods ending up in the wrong
  interface.

Eric Christopher adc4bc64ad Remove the default subtarget from the new Nios2 port. It's unused and deprecated.

Nikolai Bozhenov ebbde1409f [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.
