workaround for llvm: delete coroutine allocation elision

maybe this can be reverted, but it seems to be related
to llvm's coro transformations crashing.

fix type_is_codegen_pointer being used incorrectly
...
The names of these functions should probably change, but at least
the semantics are correct now:
* type_is_codegen_pointer - the type is either a fn, ptr, or promise
* get_codegen_ptr_type -
- ?&T and &T returns &T
- ?promise and promise returns promise
- ?fn()void and fn()void returns fn()void
- otherwise returns nullptr
