  [LV] Restrict widest induction type to be IntegerType (NFC) (#128173)

As the name of the function suggests, convertPointerToIntegerType should
return an IntegerType instead of a Type, and should only ever be called
with integer or ptr type. Fix the callers getWiderType, and
addInductionPhi to narrow the type of WidestIndTy to IntegerType,
stripping unclear casts. While at it, rename convertPointerToIntegerType
and getWiderType for clarity.
