This CL retricts shorthand notation printing to only the bounds that can be roundtripped unambiguously; i.e.: 1. ()[]->(%some_cst) ()[] 2. ()[s0]->(s0) ()[%some_symbol] Upon inspection it turns out that the constant case was lossy so this CL also updates it. Note however that fixing this issue exhibits a potential issues in unroll.mlir. L488 exhibits a map ()[s0] -> (1)()[%arg0] which could be simplified down to ()[]->(1)()[]. This does not seem like a bug but maybe an undesired complexity in the maps generated by unrolling. bondhugula@, care to take a look? PiperOrigin-RevId: 214531410
