ARM: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309755

- More refactoring. This gets rid of all of the getOpcode calls. - 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
