Use raw type for kclass references in dynamic invocation code gen (#911)

* Use raw type for kclass references in dynamic invocation code gen

Added a compile-only regression test
Resolves #905

* Make it actually generic

* Mostly fix generation

Will need to wait for inlined instantiation to merge

* Fix rebase issues and use newInstance
