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) {
            ^

-/// This file defines the VPlanHCFGBuilder class which contains the public
-/// interface (buildHierarchicalCFG) to build a VPlan-based Hierarchical CFG
-/// (H-CFG) for an incoming IR.
-///
-/// A H-CFG in VPlan is a control-flow graph whose nodes are VPBasicBlocks
-/// and/or VPRegionBlocks (i.e., other H-CFGs). The outermost H-CFG of a VPlan
-/// consists of a VPRegionBlock, denoted Top Region, which encloses any other
-/// VPBlockBase in the H-CFG. This guarantees that any VPBlockBase in the H-CFG
-/// other than the Top Region will have a parent VPRegionBlock and allows us
-/// to easily add more nodes before/after the main vector loop (such as the
-/// reduction epilogue).
