Subject: [PATCH 1/2] [VPlan] Introduce ExitPhi VPInstruction, use to create
 phi for FOR.

This patch introduces a new ExitPhi VPInstruction which creates a phi in
a leaf block of a VPlan. The first use is to create the phi node for
fixed-order recurrence resume values in the scalar preheader.

The VPInstruction takes 2 operands: 1) the incoming value from the
middle-block and a default value to be used for all other incoming
blocks.

In follow-up changes, it will also be used to create phis for reduction and
induction resume values.
