    tc-i386.c s_insn and input_line_pointer
    
    A comment in check_Scc_OszcOperations says:
          /* No need to save/restore input_line_pointer; that's done in the
             caller already.  */
    That isn't true always.  Fix a case where input_line_pointer is not
    restored and ignore_rest_of_line() accesses a wild pointer.
    
            * gas/config/tc-i386.c (s_insn <bad>): Restore input_line_pointer.
