Fix 2005-05-12-Int64ToFP

The issue is there is no unsigned -> double conversion, only signed. So I
need to test the sign and do a different thing depending on it. Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*. Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.
