[frontend] Added support in FrontendOptions for denoting the primary input. When a primary input is specified, output will only be generated for that input. (If a primary input is not specified, output will be generated for the whole module.) This commit only adds the storage for the primary input; the primary input is not yet honored by the frontend, nor is it possible to specify the primary input. Swift SVN r12148
