  Log Message:
  -----------
  [VPlan] Add all blocks to outer loop if present during ::execute (NFCI).

This ensures that all blocks created during VPlan execution are properly
added to an enclosing loop, if present.

Split off from https://github.com/llvm/llvm-project/pull/108378 and also
needed once more of the skeleton blocks are created directly via VPlan.

This also allows removing the custom logic for early-exit loop
vectorization added as part of
https://github.com/llvm/llvm-project/pull/117008.
