  -----------
  [SandboxVec][BottomUpVec] Implement pack of scalars (#115549)

This patch implements packing of scalar operands when the vectorizer
decides to stop vectorizing. Packing is implemented with a sequence of
InsertElement instructions.

Packing vectors requires different instructions so it's implemented in a
follow-up patch.
