- This change also makes it possible to switch between ARM / Thumb on a per-function basis. - Fixed thumb2 routine which expand reg + arbitrary immediate. It was using using ARM so_imm logic. - Use movw and movt to do reg + imm when profitable. - Other code clean ups and minor optimizations. llvm-svn: 77300
