Dan Gohman e832693acb When forming SSE min and max nodes for UGE and ULE comparisons, it's ...

necessary to swap the operands to handle NaN and negative zero properly.

Also, reintroduce logic for checking for NaN conditions when forming
SSE min and max instructions, fixed to take into consideration NaNs and
negative zeros. This allows forming min and max instructions in more
cases.
