  -----------
  [VPlan] Add VPInstruction to unpack vector values to scalars. (#155670)

Add a new Unpack VPInstruction (name to be improved) to explicitly
extract scalars values from vectors.

Test changes are movements of the extracts: they are no generated
together and also directly after the producer.

Depends on https://github.com/llvm/llvm-project/pull/155102 (included in
PR)
