aa6f0f3b3b Added O_F32 and O_64 in addition to UO_F32 and UO_64 even though by 
default they call the same libgcc routine. The result of the calls are
"tested" differently.

This allows us to eliminate many temporary vectors, and theirassociated malloc/free pairs.

  negative offset.

8959334b96 Make this a *real* header:

  2. Remove unneeded #includes.
  3. Add #include guard.

659afcca15 Change constant folding APIs to take an optional TargetData, and change 
ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array
of operands + size, instead of an std::vector.

In some cases, switch to using a SmallVector instead of a vector.
This allows us to get rid of some special case gross code that was there
to avoid the cost of constructing a vector.
