Krzysztof Parzyszek 0bd55a7608 [Hexagon] Custom lower VECTOR_SHUFFLE and EXTRACT_SUBVECTOR for HVX
If the mask of a vector shuffle has alternating odd or even numbers
starting with 1 or 0 respectively up to the largest possible index
for the given type in the given HVX mode (single of double) we can
generate vpacko or vpacke instruction respectively.

E.g.
  %42 = shufflevector <32 x i16> %37, <32 x i16> %41,
                      <32 x i32> <i32 1, i32 3, ..., i32 63>
  is %42.h = vpacko(%41.w, %37.w)

Patch by Pranav Bhandarkar.

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.
