Right `__managed__` var is special. Its address is set by runtime, therefore it is not a constant. nvcc does not treat it as constant either. https://godbolt.org/z/jK534MxfG I will fix it.

BTW I just found a regression related to templates in CodeGenCUDA/host-used-device-var.cu. I will fix that and update this patch.
