  -----------
  [VPlan] Simplify exituser handling by generating all extracts first(NFCI)

Simplify the handling of exit users by generating all extracts first
(safe option), and have FOR handling optimize the extracts, similar to
already done for reductions and inductions.

NFC modulo first-order recurrence extract order in middle block.
