Hello Krzysztof,

Thanks for taking a look!
This new patch should address your comments here.  Please let me know if I missed anything.

- Rebase to trunk.
- Change leading case on a number of functions/parameters/variables.  Change debug location names to dl.
- Remove some static_casts by using MF.getSubtarget<ARCSubtarget>() where appropriate.
- Return ARCRegisterInfo* where appropriate.
- Use MBB.findDebugLoc(MBBI) in a number of places where MBBI can be end().
- Remove unnecessary TII variables.
- Remove function names from a number of comments.
- Remove other misleading/unnecessary comments, or commented out code.
- Change int32_t vars to not be declared auto, and remove explicit casts.
- Remove unnecessary isGPR32Register routine, and use ARC::GPR32RegClass.contains instead.
- Use dbgs() << MI for MachineInstrs where appropriate.
- Remove printMemOperand declaration (we use printMemOperandRI).
