This commit does some refactoring to make defining assembly codelets smaller, and fixes compiler redefinition warnings. It also allows for other assembly versions to reuse the same boilerplate code as x86. Finally, it also adds the out_of_place flag to all assembly codelets. This changes nothing, as out-of-place operation was assumed to be available anyway, but this makes it more explicit.
