  -----------
  [X86] combinePredicateReduction - attempt to fold subvector all_of(icmp_eq()) / any_of(icmp_ne()) to integers

Noticed while working on Issue #59867 and Issue #53419 - there's still more to do here, but for "all vector" comparisons, we should try to cast to a scalar integer for sub-128bit types
