PRE actually would perform the optimization on these two cases, but it sees the
cast as an induction variable.
Found partial redundancy for expression (short unsigned int) VH.29 (VH.37)
Skipping insertion of phi for partial redundancy: Looks like an induction
variable
I will change it to decide that only binary expressions are induction
variables, for the moment.
