- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77300 91177308-0d34-0410-b5e6-96231b3b80d8
