*	[Hexagon] Custom lower VECTOR_SHUFFLE and EXTRACT_SUBVECTOR for HVX	Krzysztof Parzyszek	2016-07-29	1	-0/+47
	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. llvm-svn: 277168
