Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Chandler Carruth edb12a838a [TI removal] Make variables declared as `TerminatorInst` and initialized
by `getTerminator()` calls instead be declared as `Instruction`.

This is the biggest remaining chunk of the usage of `getTerminator()`
that insists on the narrow type and so is an easy batch of updates.
Several files saw more extensive updates where this would cascade to
requiring API updates within the file to use `Instruction` instead of
`TerminatorInst`. All of these were trivial in nature (pervasively using
`Instruction` instead just worked).

Diego Caballero 3587150fcb [VPlan] Introduce VPLoopInfo analysis.
The patch introduces loop analysis (VPLoopInfo/VPLoop) for VPBlockBases.
This analysis will be necessary to perform some H-CFG transformations and
detect and introduce regions representing a loop in the H-CFG.

Diego Caballero 2a34ac86d3 [VPlan] Introduce VPlan-based dominator analysis.
The patch introduces dominator analysis for VPBlockBases and extend
VPlan's GraphTraits specialization with the required interfaces. Dominator
analysis will be necessary to perform some H-CFG transformations and
to introduce VPLoopInfo (LoopInfo analysis on top of the VPlan representation).

Diego Caballero d09530144a [VPlan][LV] Introduce condition bit in VPBlockBase
This patch introduces a VPValue in VPBlockBase to represent the condition
bit that is used as successor selector when a block has multiple successors.
This information wasn't necessary until now, when we are about to introduce
outer loop vectorization support in VPlan code gen.

Andrei Elovikov d34b765cb2 [NFC][VPlan] Wrap PlainCFGBuilder with an anonymous namespace.
Summary:
It's internal to the VPlanHCFGBuilder and should not be visible outside of its
translation unit.

Nicola Zaghen 03d0b91f43 Remove DEBUG macro.
Now that the LLVM_DEBUG() macro landed on the various sub-projects
the DEBUG macro can be removed.
Also change the new uses of DEBUG to LLVM_DEBUG.

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.
