Chandler Carruth 2fdec16fbe [x86] Teach the x86 DAG combiner to form UNPCKLPS and UNPCKHPS 
instructions from the relevant shuffle patterns.

This is the last tweak I'm aware of to generate essentially perfect
v4f32 and v2f64 shuffles with the new vector shuffle lowering up through
SSE4.1. I'm sure I've missed some and it'd be nice to check since v4f32
is amenable to exhaustive exploration, but this is all of the tricks I'm
aware of.

With AVX there is a new trick to use the VPERMILPS instruction, that's
coming up in a subsequent patch.

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
