[vm/compiler] Teach compiler to fold load of type_args_len from constant args desc. This allows optimizer to eliminate redundant code branching on type_args_len which arises when inlining generic methods. Start refactoring how loads of native fields are represented: instead of simply setting a bunch of unrelated attributes introduce NativeFieldDesc structure that captures attributes of native fields, which don't have representation as Field objects. Over the time we should be able to eliminate "raw" LoadField/StoreInstanceField instructions that just address fields by their offset and use NativeFieldDesc-s in load forwarding to disambiguate different native fields that happen to have the same offset.
