SILGen: Allow partial applications of initializers.

A few spot fixes here to code that until now assumed it never had to deal with initializers. First, we have to get the "self" metatype parameter correct in the curry thunk; "self" in the initializer body is semantically the instance being constructed, so we can't follow the body param patterns. Instead, we can mostly reuse the logic for curried enum element constructors. getNextUncurryLevelRef also needs a small tweak to correctly dynamically dispatch any kind of decl, not just FuncDecls.
