Krzysztof Parzyszek a6d4fc0e29 [Hexagon] Use shuffles when lowering "gather" shufflevectors 
Shufflevector instructions in LLVM IR that extract a subset of elements
of a longer input into a shorter vector can be done using VECTOR_SHUFFLEs.
This will avoid expanding them into constly extracts and inserts.
