We can expand the init intrinsic to create a descriptor for the nested procedure by combining the entry point and TOC pointer from the global descriptor with the nest argument. The normal indirect call sequence then calls the nested procedure through the descriptor like all other calls. Patch also implements support for a nest parameter by mapping it to gpr 11.
