We don't need tests for truncating the result. There's nothing special about those truncates. We can test llrint/llround for 64-bit and 32-bit targets in the same file. Same with lrint/lround with i32 result result. lrint/lround with 64-bit result should only occur on a 64-bit target. Add some missing tests for f80 conversions.
