rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

This speeds up -iv-users by around 15% on several testcases.

The information is already available with "opt -analyze". The DominatorTree
does also not have this in its runOnFunction. So they behave now
more consistent.

AddRecs so that it checks for overflow in the computation that it is
performing, rather than just checking hasNo{Signed,Unsigned}Wrap, since
those flags are for a different computation. This fixes a bug that
impacts an upcoming change.
