Jingu Kang a1f6b21702 [ValueTracking] Handle two PHIs in isKnownNonEqual() 
loop:
  %cmp.0 = phi i32 [ 3, %entry ], [ %inc, %loop ]
  %pos.0 = phi i32 [ 1, %entry ], [ %cmp.0, %loop ]
  ...
  %inc = add i32 %cmp.0, 1
  br label %loop

On above example, %pos.0 uses previous iteration's %cmp.0 with backedge
according to PHI's instruction's defintion. If the %inc is not same among
iterations, we can say the two PHIs are not same.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
