  [LoopInterchange] Consolidate induction and reduction vars check (#203197)

Previously, the handling of PHI nodes in loop headers was scattered. In
particular, there were two separate functions, `findInductions` and
`findInductionAndReductions`, which made the code difficult to reason
about. This patch consolidates these two functions, along with their
related caller logic, into a single function,
`checkInductionsAndReductions`. Although some remarks and debug outputs
have changed as a result, I believe the functionality itself remains
unchanged.
