Summary: The attached test case fails with "fatal error: error in backend: misaligned pc-relative fixup value" as the jump table is misaligned. The EmitAlignment existed already for ARM and Thumb-1 code, but was missing for Thumb-2. The test checks that the fatal error disappears when generating an obj file, as well as checking the align directive is there when producing an asm file.
