Rosie Sumpter de55f5a044 [CostModel][AArch64] Improve cost model for vector reduction intrinsics 
OR, XOR and AND entries are added to the cost table. An extra cost
is added when vector splitting occurs.

This is done to address the issue of a missed SLP vectorization
opportunity due to unreasonably high costs being attributed to the vector
Or reduction (see: https://bugs.llvm.org/show_bug.cgi?id=44593).

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.
