Evgeniy Brevnov acfc785c0e Preserve aliasing info during memory intrinsics lowering
By specification, source and destination of llvm.memcpy.* must either be equal or non-overlapping. This semantics is hard or impossible to figure out once lowered. This patch explicitly marks loads from source and stores to destination as not aliasing if source and destination is known to be not equal.

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

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
