fib.c: Reduced the iteration from 40 to 30.

2013-11-05  Balaji V. Iyer  <balaji.v.iyer@intel.com>

        * c-c++-common/cilk-plus/CK/fib.c: Reduced the iteration from
        40 to 30.  Replaced iteration variable with a #define.  Instead of
        returning non-zero value for error, called __builtin_abort ().  Fixed
        a bug of calling fib_serial in serial case instead of fib.
        * c-c++-common/cilk-plus/CK/fib_init_expr_xy.c: Likewise.
        * c-c++-common/cilk-plus/CK/fib_no_return.c: Likewise.
        * c-c++-common/cilk-plus/CK/fib_no_sync.c: Likewise.
        * gcc.dg/cilk-plus/cilk-plus.exp: Removed duplicate/un-necessary
        compiler flag testing.
