Another oddly-named utility function with poorly-defined behavior. It returned true for archetypes, generic parameters, existential types, and metatypes of existential types. However, it would return false for dependent member types, or metatypes of archetypes, and so on. All the callers were doing something bad to begin with, so changing them over to more precise predicates improved the code. In particular, this simplifies substitution construction in the SIL parser, and makes it stricter, which turned up a couple of mistakes in the SIL tests where we were doing stuff with non-conforming types.
