Jingu Kang d8d1189bdb [AArch64] Improve SAD pattern 
Given a vecreduce_add node, detect the below pattern and convert it to the node
sequence with UABDL, [S|U]ADB and UADDLP.

i32 vecreduce_add(
 v16i32 abs(
   v16i32 sub(
    v16i32 [sign|zero]_extend(v16i8 a), v16i32 [sign|zero]_extend(v16i8 b))))
=================>
i32 vecreduce_add(
  v4i32 UADDLP(
    v8i16 add(
      v8i16 zext(
        v8i8 [S|U]ABD low8:v16i8 a, low8:v16i8 b
      v8i16 zext(
        v8i8 [S|U]ABD high8:v16i8 a, high8:v16i8 b

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.
