This adds alignment support for GlobalOp, LoadOp, and StoreOp. Tests which failed because cir.store/cir.load now print alignment were updated with wildcard matches, except where the alignment was relevant to the test. Tests which check for cir.store/cir.load in cases that don't have explicit alignment were not updated. New tests for alignment are alignment.c, align-load.c, and align-store.c.
