Dinar Temirbulatov abd1b29772 [SLPVectorizer] Failure to beneficially vectorize 'copyable' elements in integer binary ops. 
Patch tries to improve vectorization of the following code:

void add1(int * __restrict dst, const int * __restrict src) {
  *dst++ = *src++;
  *dst++ = *src++ + 1;
  *dst++ = *src++ + 2;
  *dst++ = *src++ + 3;
}
Allows to vectorize even if the very first operation is not a binary add, but just a load.

Low Level Virtual Machine (LLVM)
================================

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.
