[PATCH] Introducing initial UseAuto transform

[Sean Silva]

  Hi Edwin,

  Pending <http://llvm-reviews.chandlerc.com/D339>, could you start thinking about what user-facing documentation will be provided for this transform?

  If this patch gets committed before the documentation infrastructure is in place, I would like you to follow up and add proper user-facing documentation in a later patch once the infrastructure is setup (I will probably reach out to you once it is in place).
