re PR target/39768 (internal compiler error: RTL check: expected code 'const_int', have 'reg' in gen_rotlsi3, at config/bfin/bfin.md:1616)

2011-05-03  Stuart Henderson  <shenders@gcc.gnu.org>

        From Bernd Schmidt
        * config/bfin/bfin.md (rotrsi, rotlsi): Don't take INTVAL of anything
        that's not CONST_INT.  Seemingly redundant check is due to PR39768.
