Chris Lattner d4bcc9011b Fix three bugs: ...

1) evaluate [v]fcmp true/false with undefs to true or false instead
   of undef.
2) fix vector comparisons with undef to return a vector result instead 
   of i1
3) fix vector comparisons with evaluatable results to return vector
   true/false instead of i1 true/false (PR2529)
