Nate Begeman 9d121924fd 2nd attempt, fixing SSE4.1 issues and implementing feedback from duncan. ... PR2957 ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. llvm-svn: 70225		2009-04-27 18:41:29 +00:00
