  Log Message:
  -----------
  [VPlan] Create IR basic block for middle.block in VPlan.

Create a IR BB directly for the middle.block, instead of creating the IR
BB during skeleton creation and then replacing the middle VPBB with a
VPIRBB.

This moves another part of skeleton creation to VPlan and simplififes
the code slightly by removing code to disconnect the middle block and
vector preheader + the corresponding DT update.

NFC modulo IR block naming and block creation order, which changes the
IR names for the blocks.
