\| \| \| \| \| \|	shift/xor/sub when it is possible. Fixed a bug in SDIV, where the const operand is not a splat constant vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184931 91177308-0d34-0410-b5e6-96231b3b80d8
*	X86: Fold EXTRACT_SUBVECTORs of a BUILD_VECTOR into a smaller BUILD_VECTOR.	Benjamin Kramer	2013-03-07
\| \| \| \| \| \| \| \| \| \|	That can usually be lowered efficiently and is common in sandybridge code. It would be nice to do this in DAGCombiner but we can't insert arbitrary BUILD_VECTORs this late.
