Whitney Tsang eda454c56f [LoopFusion] Move instructions from FC0.Latch to FC1.Latch. 
Summary:This PR move instructions from FC0.Latch bottom up to the
beginning of FC1.Latch as long as they are proven safe.

To illustrate why this is beneficial, let's consider the following
example:
Before Fusion:
header1:
  br header2
header2:
  br header2, latch1
latch1:
  br header1, preheader3
preheader3:
  br header3
header3:
  br header4
header4:
  br header4, latch3
latch3:
  br header3, exit3

After Fusion (before this PR):
header1:
  br header2
header2:
  br header2, latch1
latch1:
  br header3
header3:
  br header4
header4:
  br header4, latch3
latch3:
  br header1, exit3

Note that preheader3 is removed during fusion before this PR.
Notice that we cannot fuse loop2 with loop4 as there exists block latch1
in between.
This PR move instructions from latch1 to beginning of latch3, and remove
block latch1. LoopFusion is now able to fuse loop nest recursively.

After Fusion (after this PR):
header1:
  br header2
header2:
  br header3
header3:
  br header4
header4:
  br header2, latch3
latch3:
  br header1, exit3

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.
