This adds a check for exported inline functions, that there is a definition in the definition domain (which, in practice, can only be the module purview but before any PMF starts) since the PMF definition domain cannot contain exports. This is: [dcl.inline]/7 If an inline function or variable that is attached to a named module is declared in a definition domain, it shall be defined in that domain. The patch also amends diagnostic output by excluding the PMF sub-module from the set considered as sources of missing decls. There is no point in telling the user that the import of a PMF object is missing - since such objects are never reachable to an importer. We still show the definition (as unreachable), to help point out this. Differential Revision: https://reviews.llvm.org/D128328
