[SDAG] Clarify behavior of scalable demanded/undef elts in isSplatValue [nfc]

Update comment, and add an assertion to check property expected by sole (non-test) caller.  Remove tests which appear to have been copied from fixed vector tests, and whose demanded bits don't correspond to the way this interface is otherwise used.
