Justin Holewinski a1535e3b9b [NVPTX] Honor alignment on vector loads/stores 
We were not considering the stated alignment on vector loads/stores,
leading us to generate vector instructions even when we do not have
sufficient alignment.

Now, for IR like:

  %1 = load <4 x float>, <4 x float>* %ptr, align 4

we will generate correct, conservative PTX like:

  ld.f32 ... [%ptr]
  ld.f32 ... [%ptr+4]
  ld.f32 ... [%ptr+8]
  ld.f32 ... [%ptr+12]

Or if we have an alignment of 8 (for example), we can
generate code like:

  ld.v2.f32 ... [%ptr]
  ld.v2.f32 ... [%ptr+8]

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

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, 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're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
