[X86][AVX512] Detect repeated constant patterns in BUILD_VECTOR suitable for broadcasting. Check if a build_vector node includes a repeated constant pattern and replace it with a broadcast of that pattern. For example: "build_vector <0, 1, 2, 3, 0, 1, 2, 3>" would be replaced by "broadcast <0, 1, 2, 3>" Differential Revision: https://reviews.llvm.org/D26802 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@288804 91177308-0d34-0410-b5e6-96231b3b80d8
