added tests for fegetround and fesetround in psxtests / psxfenv01
fegetround fails to send the rounding direction due to soft float and
returns to_nearest or zero in the cases
fesetround sends zero if the rounding direction is set and sends anything
else if the function fails to set the rounding direction
can you check the patch for correctness
