    arc: Remove '^' print punct character
    
    The '^' was used to print '@' character in the ouput assembly. This is
    not anylonger required by the ARC binutils. Remove it.
    
    gcc/
    
            * config/arc/arc.cc (arc_init): Remove '^' punct char.
            (arc_print_operand): Remove related code.
            * config/arc/arc.md: Update patterns which uses '%&'.
    
    gcc/testsuite/
    
            * gcc.target/arc/loop-3.c: Update test.
