Modular Codegen: Add/use a bit in serialized function definitions to track whether they are the subject of modular codegen Some decls are created not where they are written, but in other module files/users (implicit special members and function template implicit specializations). To correctly identify them, use a bit next to the definition to track the modular codegen property. Discussed whether the module file bit could be omitted in favor of reconstituting from the modular codegen decls list - best guess today is that the efficiency improvement of not having to deserialize the whole list whenever any function is queried by a module user is worth it for the small size increase of this redundant (list + bit-on-def) representation.

Modular Codegen: Support homing debug info for types in modular objects Matching the function-homing support for modular codegen. Any type implicitly (implicit template specializations) or explicitly defined in a module is attached to that module's object file and omitted elsewhere (only a declaration used if necessary for references). llvm-svn: 299987

Ensure there are only two modular codegen decls (one for the class, one for the
function - none for the class and function templates).
