New Revision: 155440

URL: http://llvm.org/viewvc/llvm-project?rev=155440&view=rev
Log:
AVX2: The BLENDPW instruction selects between vectors of v16i16 using an i8
immediate. We can't use it here because the shuffle code does not check that
the lower part of the word is identical to the upper part.
