Lower BUILD_VECTOR to SHUFFLE + INSERT_VECTOR_ELT for X86 - If INSERT_VECTOR_ELT is supported (above SSE2, either by custom sequence of legal insn), transform BUILD_VECTOR into SHUFFLE + INSERT_VECTOR_ELT if most of elements could be built from SHUFFLE with few (so far 1) elements being inserted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166288 91177308-0d34-0410-b5e6-96231b3b80d8
