Galina Kistanova 083ea389d6 Reverted r332654 as it has broken some buildbots and left unfixed for a long time.
The introduced problem is:
llvm.src/lib/Transforms/Vectorize/VPlanVerifier.cpp:29:13: error: unused function 'hasDuplicates' [-Werror,-Wunused-function]
static bool hasDuplicates(const SmallVectorImpl<VPBlockBase *> &VPBlockVec) {

Diego Caballero f58ad3129c [LV][VPlan] Build plain CFG with simple VPInstructions for outer loops.
Patch #3 from VPlan Outer Loop Vectorization Patch Series #1
(RFC: http://lists.llvm.org/pipermail/llvm-dev/2017-December/119523.html).

Expected to be NFC for the current inner loop vectorization path. It
introduces the basic algorithm to build the VPlan plain CFG (single-level
CFG, no hierarchical CFG (H-CFG), yet) in the VPlan-native vectorization
path using VPInstructions. It includes:
  - VPlanHCFGBuilder: Main class to build the VPlan H-CFG (plain CFG without nested regions, for now).
  - VPlanVerifier: Main class with utilities to check the consistency of a H-CFG.
  - VPlanBlockUtils: Main class with utilities to manipulate VPBlockBases in VPlan.

Reviewers: rengolin, fhahn, mkuper, mssimpso, a.elovikov, hfinkel, aprantl.

Gil Rapaport 8b9d1f3c5b [LV] Model masking in VPlan, introducing VPInstructions
This patch adds a new abstraction layer to VPlan and leverages it to model the planned
instructions that manipulate masks (AND, OR, NOT), introduced during predication.

The new VPValue and VPUser classes model how data flows into, through and out
of a VPlan, forming the vertices of a planned Def-Use graph. The new
VPInstruction class is a generic single-instruction Recipe that models a
planned instruction along with its opcode, operands and users. See
VectorizationPlan.rst for more details.
