the inliner pass now passes targetdata down through the inliner api's

The inliner/cloner can now optionally take TargetData info, which can be
used by constant folding.

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.
