    Apply llvm fix for crash building julia on PowerPC64
    Merge commit 6710b21d4698 from llvm git (by Kai Luo):
      [PowerPC] Allow llvm.ppc.cfence to accept pointer types
      In the context of atomic load, integer, pointer and float point types are allowed, thus we should allow llvm.ppc.cfence to accept any type mentioned.
