Since these are string attributes there is probably not much value in testing different string values for every attribute (i.e. ieee, preserve-sign)? Or is there specific reason for testing the different strings? Instead I would have a test for every attribute with possible different strings? So three tests here and three tests in the file below which exercises the lowering to LLVM IR.
