  -----------
  [SLP][NFC]Cache isUsedOutsideBlock results in gather-shuffle analysis

Hoist loop-invariant predicates and memoize per-UserTE
all_of(Scalars, isUsedOutsideBlock) in
isGatherShuffledSingleRegisterEntry and vectorizeTree to avoid
redundant walks over scalar user lists in the gather-shuffle hot path.
