gcc.c: Split out Objective-C specs to...

        * gcc.c: Split out Objective-C specs to...
        * objc/lang-specs.h: here. (New file.) Make the specs cpplib
        aware.
        * c-lex.c (init_parse): Always initialize the filename global.
        * objc/objc-act.c (lang_init): Always call check_newline at
        beginning of file.
