I prefer typeIsScalarFPArith to typeIsLegalScalarFP since it doesn't have the word `legal` in it. I think the word legal is unnecessary since it will go into a `legalIf` which makes it redundant. I like ScalarFPArith better than ScalarFP since it will suggest that not all ScalarFP instructions use it.
