llvmpipe: avoid overflow in triangle culling
Avoid multiplying fixed-point values. Calculate triangle area in
floating point use that for culling.
Lift area calculations up a level as we are already doing this in the
triangle_both() case.
Would like to share the calculated area with attribute interpolation,
but the way the code is structured makes this difficult.
